General DescriptionThe MICRF500 is a single chip UHF transceiver designed forspread spectrum communication (FHSS) intended for ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands from 700MHz to 1100MHz with FSK data rates up to 128k baud.The transmitter consists of a PLL frequency synthesizer and a power amplifier. The frequency synthesizer consists of a voltage-controlled oscillator (VCO), a crystal oscillator, dual-modulus prescaler, programmable frequency dividers and a phase-detector. The loop filter is external for flexibility and can be a simple passive circuit. The VCO is a Colpitts oscillator which requires an external resonator and varactor.FSK modulation can be applied externally to the VCO. The synthesizer has two different N, M and A frequency dividers.FSK modulation can also be implemented by switching between these dividers (max. 2400bps). The lengths of the N and M and A registers are 12, 10 and 6 bits respectively. For all types of FSK modulation, data is entered at the DATAIXO pin (see application circuit). The output power of the power amplifier can be programmed to eight levels. A lock detect circuit detects when the PLL is in lock.In receive mode the PLL synthesizer generates the local oscillator (LO) signal. The N, M and A values that give the LO frequency are stored in the N0, M0 and A0 registers. The receiver is a zero intermediate frequency (IF) type in order to make channel filtering possible with low-power integrated low-pass filters. The receiver consists of a low-noise amplifier (LNA) that drives a quadrature mixer pair. The mixer outputs feed two identical signal channels in phase quadrature. Each channel includes a preamplifier, a third order Sallen-Key RC low pass filter that protects the following gyrator filter from strong adjacent channel signals and finally, a limiter. The main channel filter is a gyrator capacitor implementation of a seven-pole elliptic low pass filter. The elliptic filter minimizes the total capacitance required for a given selectivity and dynamic range. The cut-off frequency of the Sallen-Key RC filter can be programmed to four different frequencies: 10kHz,30kHz, 60kHz and 200kHz. An external resistor adjusts the cut-off frequency of the gyrator filter. The demodulator de-modulates the I and Q channel outputs and produces a digital data output. It detects the relative phase of the I and the Q channel signal. If the I channel signal lags the Q channel, the FSK tone frequency lies above the LO frequency (data ‘1’). If the I channel leads the Q channel, the FSK tone lies below the LO frequency (data ‘0’). The output of the receiver is available on the DATAIXO pin. A RSSI (Receive Signal StrengthIndicator) circuit indicates the received signal level.Micrel, Inc. • 1849 Fortune Drive • San Jose, CA 95131 • USA • tel + 1 (408) 944-0800 • fax + 1 (408) 944-0970 • A two pin serial interface is used to program the circuit.External components are necessary for RF input and output impedance matching and decoupling of power.

The dual-modulus prescaler divides the VCO-frequency by 64/65. This mode is controlled by the A-divider. There are two sets of M, N and A-frequency ing both sets in transmit mode, FSK can be implemented by switching between those two sets. The phase-detector is a frequency/phase detector with back slash pulses to mini-mize phase noise. The VCO, crystal oscillator, charge pump,lock detector and the loop filter will be described in detail below.Voltage Controlled Oscillator (VCO)C38Figure 3.VCOThe circuit schematic of the VCO with external components is shown in Figure 3. The VCO is basically a Colpitts oscilla-tor. The oscillator has an external resonator and varactor.The resonator consists of inductor L1 and the series connec-tion of capacitor C13, the internal capacitance and the capacitance of the varactor. The capacitance of the varactor (D1) decreases as the input voltage increases. The VCO frequency will therefore increase as the input voltage in-creases. The VCO has a positive gain (MHz/Volt). If neces-sary a parallel capacitor can be added next to D1 to bring the VCO tuning voltage to its middle range or VDD/2, which is measured at Pin 9 - CMPOUT.If the value of capacitor C13 becomes too small the amplitude of the VCO signal decreases, which leads to lower output power.The layout of the VCO is very critical. The external compo-nents should be placed as close to the input pin (Pin 6) as possible. The anode of D1 must be placed next to Pins 7 and 8 in the PCB layout. G round vias should be next to component pads.Crystal OscillatorThe crystal oscillator is the reference for the RF output frequency as well as for the LO frequency in the receiver. The crystal oscillator is a very critical block since very good phase and frequency stability is required. The schematic of the crystal oscillator with external components for 10MHz is shown in Figure 4. These components are optimized for acrystal with 15pF load capacitance.10MHzXOSCOUTFigure 4.Crystal OscillatorThe crystal oscillator is tuned by varying the trimming capaci-tor C20. The drift of the RF frequency is the same as the drift of crystal frequency when measured in ppm. The total differ-ence in ppm, ∆f(ppm), between the tuned RF frequency and the drifted frequency is given by:∆f(ppm) = S T × ∆T + n × ∆t where:•S T is the total temperature coefficient of the oscillator frequency (due to crystal and components) in ppm °C.•∆T is the change in temperature from room temperature, at which the crystal was tuned.•n is the ageing in ppm/year.•∆t is the time (in years) elapsed since the transceiver was last tuned.The demodulator will not be able to decode data when ∆f(Hz) = ∆f(ppm) × f RF is larger than the FSK frequency deviation. For small frequency deviations, the crystal should be pre-aged, and should have a small temperature coeffi-cient. The circuit has been tested with a 10MHz crystal, but other crystal frequencies can be used as well.Prestart of XCOThe start-up time of a crystal oscillator is typically some milliseconds. Therefore, to save current consumption, the MICRF500 circuit has been designed so that the XCO is turned on before any other circuit block. During start-up the XCO amplitude will eventually reach a sufficient level to trigger the M-counter. After counting two M-counter output pulses the rest of the circuit will be turned on. The current consumption during the prestart period is approximately 300µA.Lock DetectorThe MICRF500 circuit has a lock detector feature that indi-cates whether the PLL is in lock or not. A logic high on Pin 15(LOCKDET) means that the PLL is in lock.The phase detector output is converted into a voltage that is filtered by the external capacitor C23, connected to Pin 14,LDC. The resulting DC voltage is compared to a reference window set by bits Ref0 – Ref5. The reference window can be stepped up/down linearly between 0V, Ref0 – Ref5 = 1, and Ref0 – Ref5 = 0, which gives the highest value (DC voltage)of the reference window. The size of the window can either be equal to two (Ref6 = 1) reference steps or four reference steps (Ref6 = 0).The bit setting that corresponds to lock can vary, depending on temperature, loop filter and type of varactor. Therefore, the lock detect circuit needs to be calibrated regularly by a software routine that finds the correct bit setting, by running through all combinations of bits Ref0 – Ref5. Depending on the size of the reference window, there will be several bit combinations that show lock. For instance, with a large reference window, as much as five bit combinations can make the lock detector show lock. To have the maximum robustness to noise, the third of the bit settings should be chosen.Charge PumpThe charge pump can be programmed to four different modes with two currents, ±125µA and ±500µA. Bit 70 and 71 in the control word (cpmp1 and cpmp0) controls the operation. The four modes are:1.cpmp1=0Current is constant ±125µA. Used incpmp0=0applications where short PLL locktime is not important.2.cpmp1=0Current is constant ±500µA. Used incpmp0=1applications where a short PLL locktime is important, e.g., internal modula-tion. See “Modulation Inside PLL”section.3.cpmp1=1Current is ±500µA when PLL is out ofcpmp0=0lock and ±125µA when it is in lock.Controlled by LOCKDET (Pin 15). Locktime is halved.See “Modulation Outside PLL” section.4.cpmp1=1Same as above in Tx. In Rx the currentcpmp0=1is ±500µA. Used when using dual-loopfilters. See “Modulation Outside PLLDual-Loop Filters” section.Tuning of VCO and XCOThere are two circuit blocks that may need tuning, the VCO and the crystal oscillator.VCO TuningWhen the VCO voltage is not at its mid-point, a capacitor may be added in parallel with D1or by small increments changes in the L1 or C13 values.This is particularly important when using VCO modulation. The gain curve of the VCO (MHz/Volt) is not linear and the gain will therefore vary with loop voltage. This means that the FSK frequency deviation also varies with loop voltage. When using internal modulation, tuning the VCO can be omitted as long as the VCO gain is large enough to allow the PLL to handle variations in process parameters and tempera-ture without going out of lock.XCO TuningTune the trimming capacitor in the crystal oscillator to the precise desired transmit frequency. It is not possible to tune the crystal oscillator over a large frequency range. N, M and A values must therefore be chosen to give a RF frequency very close to the desired frequency. Because of the small tuning range the VCO will not go out of lock when tuning the crystal oscillator.FSK ModulationThe circuit has two sets of frequency dividers A0, N0, M0 and A1, N1, M1. The frequency dividers are programmed via the control word. A0, N0, M0 are to be programmed with the receive frequency and are used in receive mode. There are three ways of implementing FSK:•FSK modulation can be applied to the VCO. This way of implementing FSK modulation is ex-plained more in detail in the next section. Thevalues corresponding to the transmit frequencyshould be programmed in dividers A1, N1 andM1. Pin DATAIXO must be kept in tri-state fromthe time Tx-mode is entered until one startssending data.•FSK modulation by switching between the two sets of A, N and M dividers. A, N and M valuescorresponding to the receive frequency and bothtransmit frequencies have to be found. Intransmit the values corresponding to data ‘0’should be programmed in dividers A0, N0 andM0, and the values corresponding to data ‘1’should be programmed in dividers A1, N1 andM1.•FSK modulation by adding/subtracting 1 todivider A1. The frequency deviation will be equalto the comparison frequency. The valuescorresponding to the transmit frequency shouldbe programmed in dividers A1, N1 and M1.For all types of FSK modulation, data is entered at the DATAIXO pin.Loop FilterThe design of the loop filter is of great importance for optimizing parameters like modulation rate, PLL lock time, bandwidth and phase noise. Low bitrates will allow modula-tion inside the PLL, which means the loop will lock on different frequency for 1s and 0s. This can be implemented by switch-ing the internal dividers (M, N and A).Higher modulation rates (above 2400bps) imply implementa-tion of modulation outside the PLL. This can be implemented by applying the modulation directly to the VCO.Loop filter values can be found using an appropriate software program.Modulation Inside PLLA fast PLL requires a loop filter with relatively high bandwidth. If a second order loop filter is chosen, it may not give adequate attenuation of the comparison frequency. There-fore in the following example a third order loop filter is chosen. Example 1:Radio frequency f RF868MHzComparison frequency f C100kHzLoop bandwidth BW 3.8kHzVCO gain K o30MHz/VPhase comparator gain K d500µA/radPhase margin j62°Breakthrough suppression A20dBThe component values will be:OUTINFigure 5.Third Order Loop FilterWith this loop filter, internal modulation up to 2400bps ispossible. The PLL lock time from power-down to Rx will beapproximately 1ms.Modulation Outside PLL (Closed Loop)When modulation is applied outside the PLL, it means that thePLL should not track the changes in the loop due to themodulation signal. A loop filter with relatively low bandwidthis therefore necessary. The exact bandwidth will depend onthe actual modulation rate. Because the loop bandwidth willbe significantly lower than the comparison frequency, asecond order loop filter will normally give adequate attenua-tion of the comparison frequency. If not, a third order loop filtermay give the extra attenuation needed.Example 2:Radio frequency f RF868MHzComparison frequency f C140kHzLoop bandwidth BW900HzVCO gain K o30MHz/VPhase comparator gain K d125µA/radPhase margin j61°The component values will be:OUTINCmpRFigure 6.Second Order Loop FilterData rates above approximately 19200baud (includingManchester coding) can be used with this loop filter withoutsignificant tracking of the modulating signal. PLL lock time willbe approximately 4ms.If a faster PLL lock time is wanted, the charge pump can bemade to deliver a current of 500µA per unit phase error, whilean open drain NMOS on chip (Pin 10, CmpR) switches in asecond damping resistor (R10) to ground as shown in Figure6. Once locked on the correct frequency, the PLL automati-cally returns to standard low noise operation (charge pumpcurrent: 125µA/rad). If correct settings have been made in thecontrol word (cpmp1=1, cpmp0=0), the fast locking featureis activated and will reduce PLL lock time by a factor of twowithout affecting the phase margin in the loop.Components C17, C18 C19, R11, R12 and R13 (see applica-tion circuit) are necessary if FSK modulation is applied to theVCO. Data entered at the DATAIXO pin will then be fedthrough the Mod pin (Pin 11) which is a current output. The pinsources a current of 50µA when Logic 1 is entered at theDATAIXO and drains the current for Logic 0. The capacitanceof C17 will set the order of filtering of the baseband signal. Alarge capacitance will give a slow ramp-up and therefore ahigh order of filtering of the baseband signal, while a smallcapacitance gives a fast ramp-up, which in turn also gives abroader frequency spectrum. Resistors R11 and R12 set thefrequency deviation. If C18 is large compared to C17, thefrequency deviation will be large. R13 should be large toavoid influencing the loop filter. Pin DATAIXO must be keptin tri-state from the time Tx-mode is entered until one startssending data.Modulation Outside PLL, Dual-Loop FiltersModulation outside the PLL requires a loop filter with arelatively low bandwidth compared to the modulation rate.This results in a relatively long loop lock time. In applicationswhere modulation is applied to the VCO, but at the same timea short start-up time from power down to receive mode isneeded, dual-loop filters can be implemented. Figure 7shows how to implement dual-loop filters.towards_VCOFigure 7.Dual-Loop FiltersThe loop filter used in transmit mode is made up of C15, C16,R9 and R10. The fast lock feature is also included (internalNMOS controlled by FLC, Fast Lock Control). This filter isautomatically switched in/out by an internal NMOS at Pin 4,QchOut, which is controlled by DFC (Dual Filter Control). BitsOutS2, OutS1, OutS0 must be set to 110. When QchOut isused to switch the Tx loop filter to ground, neither QchOut norIchOut can be used as test pins to look at the different receiversignals. The receive mode loop filter comprises C115, C116,R109, R101 and C101.Modulation Outside PLL (Open Loop)In this mode the charge pump output is tri-stated. The loop isopen and will therefore not track the modulation. This meansthat the loop filter can have a relatively high bandwidth, whichgive short switching times. However, the loop voltage willdecrease with time due to current leakage. The transmit timewill therefore be limited and is dependent on the bandwidth ofthe loop filter. High bandwidth gives low capacitor values andthe loop voltage will decrease faster, which gives a shortertransmit time.The loop is closed until the PLL is locked on the desiredfrequency and the power amplifier is turned on. The loopimmediately opens when the modulation starts. The loop willnot track the modulation, but the modulation still needs to beDC free due to the AC coupling in the modulation network.TransmitPower Amplifier (PA)The power amplifier is biased in class AB. The last stage has an open collector, and an external load inductor (L2) is therefore necessary. The DC current in the amplifier is adjusted with an external bias resistor (R14). A good starting point when designing the PA is a 1.5kΩ bias resistor which gives a bias current of approximately 50µA. This will give a bias current in the last stage of about 15mA.The impedance matching circuit will depend on the type of antenna used, but should be designed for maximum output power. For maximum output power the load seen by the PA must be resistive and should be about 100Ω. The output power is programmable in eight steps, with approximately 3dB between each step. This is controlled by bits Pa2 - Pa0. To prevent spurious components from being transmitted the PA should be switched on/off slowly, by allowing the bias current to ramp up/down at a rate determined by the external capacitor C25 connected to Pin 24. The ramp up/down current is typically 1.1µA, which makes the on/off rate for a 3.0V power supply 2.6µs/pF. Turning the PA on/off affects the PLL. Therefore the on/off rate must be adjusted to the PLL bandwidth.PA BufferA buffer amplifier is connected between the VCO and the PA to ensure that the input signal of the PA has sufficient amplitude to achieve the desired output power. This buffer can be bypassed by setting the bit Gc to 0.ReceiveFront End (LNA and Mixers)A low noise amplifier in RF receivers is used to boost the incoming signal prior to the frequency conversion process. This is important in order to prevent mixer noise from domi-nating the overall front end noise performance. The LNA is a two-stage amplifier and has a nominal gain of 23dB at 900MHz. The LNA has a dc feedback loop, which provides bias for the LNA. The external capacitor C26 decouples and stabilizes the overall dc feedback loop, which has a large low frequency loop gain. Figure 8 shows the input impedance of the LNA. Input matching is very important to get high receive sensitivity.The LNA can be bypassed by setting bit ByLNA to ‘1’. This is useful for very strong signal levels.The RSSI signal can be used to drive a microcontroller in a way when a strong RF income signal is present the LNA can be bypassed. This will increase the dynamic range by ap-proximately 25dB.The mixers have a gain of about 12dB at 900MHz. The differential outputs of the mixers are available at Pins 34, 35 and at Pins 38, 39. The output impedance of each mixer is about 15kΩ.Figure 8.Input ImpedanceSallen-Key Filter and PreamplifierEach channel includes a preamplifier and a prefilter, which is a three-pole elliptic Sallen-Key low pass filter with 20dB stopband attenuation. It protects the following gyrator filter from strong adjacent channel signals. The preamplifier has a gain of 20dB when bit Gc=0 and 30dB when bit Gc=1. The output voltage swing is about 200mV PP for the 30dB gain setting and 1V PP for the 20dB gain setting.The third order Sallen-Key low pass filter is programmable to four different cut-off frequencies according to the table below: Fc1Fc0Cut-Off Frequency Recommended(kHz)Channel Spacing 0010 ±2.525kHz0130 ±7.5100kHz1060 ±15200kHz11200 ±50700kHzFor the 10kHz cut-off frequency the first pole must be gener-ated externally by connecting a 820pF capacitor between the outputs of each mixer. For the 30kHz cut-off frequency a 68pF capacitor is needed between the outputs.As the cut-off frequency of the gyrator filter can be set by varying an external resistor, the optimum channel spacing will depend on the cut-off frequencies of the Sallen-Key filter. The table above shows the recommended channel spacing depending on the different bit settings.Gyrator FilterThe main channel filter is a gyrator capacitor implementation of a seven-pole elliptic low pass filter. The elliptic filter minimizes the total capacitance required for a given selectiv-ity and dynamic range. An external resistor can adjust the cut-off frequency of the gyrator filter. The following table shows how the cut-off frequency varies with bias resistor:。

The outputs of the amplifier switch between the supply voltage and ground at high speeds while driving high currents. This high-frequency digital signal is passed through an LC low-pass filter to recover the amplified audio signal. Since the amplifier must drive the inductive LC output filter and speaker loads, the amplifier outputs can be pulled above the supply voltage and below ground by the energy in the output inductance. To avoid subjecting the TA2024B to potentially damaging voltage stress, it is critical to have a good printed circuit board layout. It is recommended that Tripath’s layout and application circuit be used for all applications and only be deviated from after careful analysis of the effects of any changes. Please contact TripathTechnology for further information regarding reference design material regarding the TA2024B.O u t p u t S t a g e l a y o u t C o n s i d e r a t i o n s a n d C o m p o n e n t S e l e c t i o n C r i t e r i a Proper PCB layout and component selection is a major step in designing a reliable TA2024Bpower amplifier. The supply pins require proper decoupling with correctly chosen components to achieve optimal reliability. The output pins need proper protection to keep the outputs from going below ground.The above layout shows ideal component placement and routing for channel 1 (the same design criteria applies to channel 2). This shows that C3, a 0.1uF surface mount 0805 capacitor, should be the first component placed and must decouple VDD1 (pins 29 and 30) directly to PGND1(pin35). C2, a low ESR, electrolytic capacitor, should also decouple VDD1 directly to PGND1.Both C2 and C3 may decouple VDD1 to a ground plane, but it is critical that the return path to the PGND1 pin of theTA2024B, whether it is a ground plane or a trace, be a short and direct low impedance path. Effectively decoupling VDD will shunt any power supply trace length inductance.The diodes and inductors shown are for channel 1’s outputs. D1 and L2 connect to the OUTP1 pin and D2 and L3 connect to the OUTM1 pin of the TA2024B. Each output must have a Schottky or Ultra Fast Recovery diode placed near the TA2024B, preferably immediately after thedecoupling capacitors and use short returns to PGND1. These low side diodes, D1 and D2, will prevent the outputs from going below ground. To be optimally effective they must have a short and direct return path to its proper ground pin (PGND1) of the TA2024B. This can be achieved with a ground plane or a trace.The output inductors, L2 and L3, should be placed close to the TA2024B without compromising the locations of the closely placed supply decoupling capacitors and output diodes. The purposeof placing the output inductors close to the TA2024B output pins is to reduce the trace length of the switching outputs. This will aid in reducing radiated emissions.Please see the External Component Description section on page 6 for more details on the above-mentioned components. The Application/ Test Circuit refers to the low side diodes as D O , The high side diodes as D H , and both supply decoupling capacitors as C SW .T A 2024B A m p l i f i e r G a i nThe ideal gain of the TA2024B is set by the ratio of two external resistors, R I and R F , and is given by the following formula: IF I O R R12V V ?=where V I is the input signal level and V O is the differential output signal level across the speaker. Please note that V O is 180° out of phase with V I .The ideal gain of the TA2024B is 12V/V, whereas typical values are: A V = 11.5V/V for 4? and 11.7V/V for 8?.P r o t e c t i o n C i r c u i t sThe TA2024B is guarded against over-temperature and over-current conditions. When thedevice goes into an over-temperature or over-current state, the FAULT pin goes to a logic HIGH state indicating a fault condition. When this occurs, the amplifier is muted, all outputs are TRI-STATED, and will float to 1/2 of V DD .O v e r -t e m p e r a t u r e P r o t e c t i o nAn over-temperature fault occurs if the junction temperature of the part exceeds approximately 155°C. The thermal hysteresis of the part is approximately 45°C, therefore the fault will automatically clear when the junction temperature drops below 110°C.O v e r -c u r r e n t P r o t e c t i o nAn over-current fault occurs if more than approximately 7 amps of current flows from any of the amplifier output pins. This can occur if the speaker wires are shorted together or if one side of the speaker is shorted to ground. An over-current fault sets aninternal latch that can only be cleared if the MUTE pin is toggled or if the part is powered down. Alternately, if the MUTE pin is connected to the FAULT pin, the HIGH output of the FAULT pin will toggle the MUTE pin and automatically reset the fault condition.O v e r l o a dThe OVERLOADB pin is a 5V logic output. When low, it indicates that the level of the input signal has overloaded the amplifier resulting in increased distortion at the output. The OVERLOADB signal can be used to control a distortion indicator light or LED through a simple buffer circuit, as the OVERLOADB cannot drive an LED directly.S l e e p P i nThe SLEEP pin is a 5V logic input that when pulled high (>3.5V) puts the part into a low quiescent current mode. This pin is internally clamped by a zener diode to approximately 6V thus allowing the pin to be pulled up through a large valued resistor (1meg ? recommended) to V DD . To disable SLEEP mode, the sleep pin should be grounded.F a u l t P i nThe FAULT pin is a 5V logic output that indicates various fault conditions within the device.These conditions include: low supply voltage, low charge pump voltage, low 5V regulator voltage, over current at any output, and junction temperature greater than approximately 155°C. All faults except overcurrent all reset upon removal of the condition. The FAULT output is capable of directly driving an LED through a series 2k ? resistor. If the FAULT pin is connected directly to the MUTE input an automatic reset will occur in the event of an over-current condition.P o w e r D i s s i p a t i o n D e r a t i n gFor operating at ambient temperatures above 25°C the device must be derated based on a 150°C maximum junction temperature, TJMAX as given by the following equation:JAA JMAXDISS )T T (P θ?=where…PDISS = maximum power dissipationTJMAX = maximum junction temperature of TA2024B TA = operating ambient temperatureθJA = junction-to-ambient thermal resistance Where θJA of the package is determined from the following graph:In the above graph Copper Area is the size of the copper pad on the PC board to which the heat slug of the TA2024B is soldered. The heat slug must be soldered to the PC Board to increase the maximum power dissipation capability of theTA2024B package. Soldering will minimize the likelihood of an over-temperature fault occurring during continuous heavy load conditions. The vias used for connecting the heatslug to the copper area on the PCB should be 0.013” diameter.P e r f o r m a n c e M e a s u r e m e n t s o f t h e T A 2024BThe TA2024B operates by generating a high frequency switching signal based on the audio input. This signal is sent through a low-pass filter (external to the Tripath amplifier) that recovers an amplified version of the audio input . The frequency of the switching pattern is spread spectrum and typically varies between 100kHz and 1.0MHz, which is well above the 20Hz –20kHz audio band. The pattern itself does not alter or distort the audio input signal but it does introduce some inaudible components.J AThe measurements of certain performance parameters, particularly noise related specifications such as THD+N, are significantly affected by the design of the low-pass filter used on the output as well as the bandwidth setting of the measurement instrument used. Unless the filter has a very sharp roll-off just beyond the audio band or the bandwidth of the measurement instrument is limited, some of the inaudible noise components introduced by the Tripath amplifiers switching pattern will degrade the measurement.One feature of the TA2024B is that it does not require large multi-pole filters to achieve excellent performance in listening tests, usually a more critical factor than performance measurements. Though using a multi-pole filter may remove high-frequency noise and improve THD+N type measurements (when they are made with wide-bandwidth measuring equipment), these same filters degrade frequency response. The TA2024B Evaluation Board uses the Test/Application Circuit in this data sheet, which has a simple two-pole output filter and excellent performance in listening tests. Measurements in this data sheet were taken using this same circuit with a limited bandwidth setting in the measurement instrument.P A C K A G E I N F O R M A T I O NThe package for the TA2024B is a 36-Lead Power Small Outline Package (PSOP), similar to JEDEC outline MO-166, variation AE.

All applicable legal or institutional installation regulations must be complied with during installation.The switch for changing the direction of rotation may only be operated by authorisedspecialists. The direction of rotation must not in particular be reversed in a frost protection circuit.The device may only be opened at the manufacturer's site. It does not contain any parts that can be replaced or repaired by the user.Cables must not be removed from the device.The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.Operating mode Converter for sensorsProduct featuresThe actuator is fitted with an integrated interface for BACnet MS/TP, Modbus RTU and MP-Bus. It receives the digital control signal from the control system and returns the current status.Connection option for a sensor (passive, active or with switching contact). In this way, the analogue sensor signal can be easily digitised and transferred to the bus systems : BACnet, Modbus or MP-Bus.Parametrisable actuators Combination analogue - communicative(hybrid mode)Simple direct mountingManual overrideAdjustable angle of rotationHigh functional reliabilityHome position Adaptation and synchronisation The factory settings cover the most common applications. Single parameters can be modified with the Belimo service tools MFT-P or ZTH EU.The communication parameters of the bus systems (address, baud rate etc.) are set with the ZTH EU. Pressing the "Address" button on the actuator while connecting the supply voltage resets the communication parameters to the factory setting.Quick addressing: The BACnet and Modbus address can alternatively be set using the buttons on the actuator and selecting 1...16. The selected value is added to the "basic address" parameter and results in the absolute BACnet and Modbus address.With conventional control by means of an analogue control signal, BACnet or Modbus can be used for the communicative position feedbackStraightforward direct mounting on the ball valve with only one central screw. The assembly tool is integrated in the plug-in position indication. The mounting orientation in relation to the ball valve can be selected in 90° steps.Manual override with push-button possible (the gear train is disengaged for as long as the button is pressed or remains locked).Adjustable angle of rotation with mechanical end stops.The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaptation, which is when the operating range and position feedback adjust themselves to the mechanical setting range.The actuator then moves into the position defined by the control signal.Factory setting: Y2 (counter-clockwise rotation).An adaptation can be triggered manually by pressing the "Adaptation" button or with the PC-Tool.
