Ensure that the voltage is correct as indicated on the voltage selector (12) and that the mains outlet is switched on. Alternatively, the amplifier can be powered by a 12V battery, such as a car or boat battery, by connecting th e “+” and “-” of the battery to the 12Vdc INPUT (14) on the rear panel. Ensure that DC cables are capable of handling the current (6A min. recommended)For CS series slave amplifiers, connect the audio input to the LINE IN connectors (19) on the rear panel using good quality RCA leads. The CS series amplifiers are mono, so any stereo signals will be summed together and reproduced as a single output. The signal maybe continued onto further amplifiers by connecting the LINE OUT connectors (18) to the LINE IN connectors of the next amplifier, again using good quality RCA leads.1.

LINE OUT connectors (RCA) 19. LINE IN connectors (RCA)For CM-series mixer amplifiers, connect any line level audio inputs to the LINE IN connectors (19) on the rear panel using good quality RCA leads. Connect a microphone (if required) to the front panel jack or combo input (1). Further amplifiers can be connected from the rear LINE OUT sockets.The CM and CS series amplifiers can be used either as 100V line amplifiers or standard low impedance power amplifiers. These 2 configurations cannot be used together, so it is important to decide which method will be used at the start.100V line systemsFor 100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire which has adequate current rating to handle the total output of the amplifier. Connect the “100V” (17) output terminal to the positive (+) connection of the speaker and “COM” output (15) to the negative (-) connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected together and all negative terminals connected together as shown below.A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many speakers can be used on a single amplifier is the power rating. For most purposes, it is advised to connect as many speakers as needed with a combined wattage of no more than 90% of the amplifier’s output power rating. The terminals of a 100V speaker are connected to a transf ormer and in some cases, this transformer may be “tapped” for different power ratings. These tappings can be used to adjust the wattage (and output volume) of each speaker in the system to help achieve the ideal total power of the system for the amplifier.Low impedance systemsThe CM and CS series amplifiers can provide an output for a single 8Ω speaker by connecting the “8Ω” output (16) to the positive (+) speaker connection and “COM” output (15) to the negative (-) speaker connection. It is important to ensure that the speaker load is no less than 8Ω and that the power handling of the speaker is equal to or greater than the output power of the amplifier. OperationWhen all connections to the amplifier are made, turn all rotary controls down and switch on the power (11) and a power LED will illuminate. Ensure a signal is being fed to the LINE IN connection and gradually increase the MASTER rotary control (5) part way for testing.. For CM mixer-amplifiers, increase the LINE IN rotary (3) until the output is heard through the speakers. Turn up the MASTER to the maximum required volume level and reduce the LINE IN control if necessary.Note: If a line input is not connected to a CM series mixer-amplifier, the initial test can be made using the built-in USB/SD audio player. See section below for instructions.If a microphone is connected, make sure it is switched on and gradually increase the MIC control (2) whilst speaking into the microphone until the required volume level is reached. The microphone sho uld not be able to “hear” the speakers, which can cause feedback (squealing or howling noise).USB/SD audio playerCM series mixer-amplifiers are fitted with a built-in USB/SD audio player. This unit allows playback of music or audio messages which are stored as standard compressed audio files on either USB pen drive or SD card.Push the USB pen drive into the USB port (3) and/or SD card into the SD card input (5) and the audio files will start to play automatically. Turn up the USB/SD rotary control gradually to hear the output from the speakers and increase to the required level. If play does not start automatically, press the USB/SD button (1) and Play/Pause button (7) to check if the player is set to play from the required memory device. Try Previous track and Next track buttons (6, 8) if the selected track is unable to play. Otherwise, check that the audio files are standard compressed type.The USB/SD button (1) switches between the USB memory device and SD card, allowing a choice of playlist and storage type. Normal playback will read through all tracks on the storage device. Press the REPEAT button (2) once to continually repeat the current track, press REPEAT again to enter the random track selection mode. Pressing the EQ button (4) steps through 5 preset equalizer settings, offering different tonal responses to suit the type of music or compensate for room acoustics.Pressing the Previous track button (6) briefly steps backwards through tracks on the memory device. Press and hold this button to decrease the playback volume.Pressing the Next track button (8) briefly steps forwards through tracks on the memory device. Press and hold this button to increase the playback volume.To pause the current track, press the Play/Pause button (7) and press it again to resume playback. The LED digital display (9) will show the track number when a track is selected and then the elapsed time when it is playing.To avoid loud pops through the speakers, turn down the MASTER control before powering down.Fog/Siren/Alert buttonsIn addition to audio controls, the CM60 front panel has 3 warning sound buttons. Pressing any of these will issue one of 3 preset warning sounds through the speakers.1. USB / SD input source selector2. REPEAT button (repeat play / random play)3.

MIC23150 4MHz 2A 切换电源寄生模式芯片说明书
MIC23150 Evaluation Board4MHz 2A Buck Regulator withHyperLight Load™HyperLight Load is a trademark of Micrel, Inc. MLF is a registered trademark of Amkor Technology.Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • General DescriptionThe MIC23150 is a 2A 4MHz switching regulator featuring HyperLight Load™ mode. The MIC23150 is highly efficient throughout the entire output current range, drawing just 23µA of quiescent current in operation. The tiny 2mm x2mm MLF ®package, in combination with the 4MHz switching frequency, enables a compact sub-1mm height solution with only three external components. The MIC23150 provides accurate output voltage regulation under the most demanding conditions and responds extremely quickly to a load transient with exceptionally small output voltage ripple.Factoring in the output current, the internal circuitry of the MIC23150 automatically selects between two modes of operation for optimum efficiency. Under light load conditions, the MIC23150 goes into HyperLight Load™mode. HyperLight Load™ uses a Pulse-Frequency Modulation (PFM) control scheme that controls the off time at light load. This proprietary architecture reduces the amount of switching needed at light load, thereby increasing operating efficiency. The MIC23150 attains up to 87% efficiency at 1mA output load. As the load current increases beyond approximately 100mA, the device operates using the Pulse-Width Modulation (PWM) method for up to 93% efficiency at higher load. The two modes of operation ensure the highest efficiency across the entire load range.The MIC23150 operates from an input voltage range of 2.7V to 5.5V and features internal power MOSFETs that deliver up to 2A of output current. This step-down regulator provides an output voltage accuracy of +/-2.5% across the junction temperature range of -40ºC to +125ºC. The MIC23150 is available in fixed output versions supporting an output voltage as low as 1.0V.RequirementsThe MIC23150 evaluation board requires an input power source that is able to deliver greater than 2A at 2.7V to the MIC23150. The output load can either be an active (electronic) or passive (resistive) load.Getting Started1. Connect an external supply to the V IN (J1)terminal . Apply the desired input voltage to V IN (J1) and ground (J2) terminals of the evaluation board, paying careful attention to polarity and supply voltage (2.7V ≤ V IN ≤ 5.5V). An ammeter may be placed between the input supply and the V IN (J1) terminal. Be sure to monitor the supply voltage at the V IN (J1) terminal, since the ammeter and/or power lead resistance can reduce the voltage supplied to the device.2. Connect a load to the V OUT (J3) and groundterminal (J4). The load can be either passive (resistive) or active (electronic load). An ammeter may be placed between the load and the output terminal. Ensure the output voltage is monitored at the V OUT (J3) terminal.3. Enable the MIC23150. The MIC23150 evaluationboard has a pull-up resistor to V IN . To disable the device, apply a voltage below 0.5V to the EN (J5)terminal. In the absence of the pull-up resistor, the device is enabled by applying a voltage greater than 1.2V to the EN (J5) terminal. The enable pin must be either pulled high or low for proper operation. Removing the pull-up resistor and leaving the pin floating will cause the regulator to operate in an unknown state.Output VoltageThe MIC23150 evaluation board is available with the following output voltage options listed below:Ordering InformationPart Number Description(2)MIC23150-CYMT EV (1) 1.0V Fixed Output Evaluation Board MIC23150-4YMT EV(1)1.2V Fixed Output Evaluation Board MIC23150-GYMT EV 1.8V Fixed Output Evaluation Board MIC23150-SYMT EV3.3V Fixed Output Evaluation BoardNote:1. Contact Micrel Marketing2. Other voltage options available on request. Contact Micrel.HyperLight Load™ ModeMIC23150 uses a minimum on and off time proprietary control loop (patented by Micrel). When the output voltage falls below the regulation threshold, the error comparator begins a switching cycle that turns the PMOS on and keeps it on for the duration of the minimum-on-time. This increases the output voltage. If the output voltage is over the regulation threshold, then the error comparator turns the PMOS off for a minimum-off-time until the output drops below the threshold. The NMOS acts as an ideal rectifier that conducts when the PMOS is off. Using a NMOS switch instead of a diode allows for lower voltage drop across the switching device when it is on. The asynchronous switching combination between the PMOS and the NMOS allows the control loop to work in discontinuous mode for light load operations. In discontinuous mode, the MIC23150 works in pulse frequency modulation (PFM) to regulate the output. As the output current increases, the off-time decreases, thus provides more energy to the output. This switching scheme improves the efficiency of MIC23150 during light load currents by only switching when it is needed. As the load current increases, the MIC23150 goes into continuous conduction mode (CCM) and switches at a frequency centered at 4MHz. The equation to calculate the load when the MIC23150 goes into continuous conduction mode may be approximated by the following formula:˜˜¯ˆÁÁËÊ¥¥->f L D V V I OUT IN LOAD 2)(As shown in the previous equation, the load at which MIC23150 transitions from HyperLight Load™ mode to PWM mode is a function of the input voltage (V IN ), output voltage (V OUT ), duty cycle (D), inductance (L) and frequency (f). As shown in Figure 1, as the Output Current increases, the switching frequency also increases until theMIC23150 goes from HyperLight Load TMmode to PWM mode at approximately 120mA. The MIC23150 will switch at a relatively constant frequency around 4MHz once the output current is over 120mA.Figure 1.

ARRIS C4 CMTS Release 8.1.5商品介绍说明书
Product FlyerC4® CMTSThe ARRIS C4 CMTS Release 8.1.5 is providing another set of major feature additions intended to increase pro tability and operational ef ciency for customers of the industry-leading DOCSIS ® 3.0 C4 CMTS. The C4 CMTS allows an operator to cost-effectively deploy DOCSIS, PacketCable™, DSG/ADSG, and PacketCable Multimedia(PCMM™) services. The C4 CMTS increases subscriber satisfaction and retention via aself-healing design that maintains system services without interruption, providingindustry-leading 99.999% system availability.With Rel. 8.1.5, ARRIS delivers another increase of density in the downstream with theeXtended Downstream Cable Access Module (XD CAM) for those operators who useAnnex A (8 MHz) downstream channels. Beginning with Rel. 8.1.5, an operator canincrease the number of Annex A downstream channels from 16 or 24 to 32.Release 8.1.5 provides a number of signi cant operations enhancements in addition to32D Annex A support for the XD CAM. Operators can con gure IS-IS to use point-to-point adjacencies. Operators can also use Dynamic Channel Change (DCC) to hitlesslymove a cable modem to a different upstream channel when it is only bonding in thedownstream direction. The C4 CMTS will take action to quickly resolve a Sequence Outof Range error condition reported by a cable modem in the CM-STATUS message.Operators can use “show tech support brief” to collect vital data in a minimal amount oftime for faster restoration of services. Storing only valid BPI certi cates can ensure thatcable modems with valid BPI certi cates will be able to register. Operators can provisionthe number of upstream equalizer taps on the C4 CMTS in Rel. 8.1.5 based on thespeci c con guration/scenario to get a more accurate signal-to-noise ratio (SN R)measurements. All of these features are supported with high availability, at maximumsubscriber density, and with independent con guration of upstream and downstreamchannels using dedicated upstream (12U and 24U) and downstream (16D and XD)CAMs. In addition, operators can trial 24 downstream channel bonding in the lab or theeld, and operators can lab trial 5 to 85 MHz support for upstream channels on the 24UCable Access Module (CAM).

Monitoring and control made simple C441 series communication modulesEaton’s motor control products offer the widestrange of communication protocol support foreasy integration into any PLC or DCS system.Both starters and soft starters use the sameC441 family of modules for communications.The modules come standard with four inputs andtwo relay outputs. C441 communication modulescan also be used independently for standaloneI/O applications.Determining your communication needsThere are many reasons to choose a particular industrial communication network. Most important is what your controller supports; after that, speed, data size, configuration, plant standards and other parameters all come into play.Need help determining which network to choose? Refer to the table below.Network configuration guideAB Maximum cable length C 500 m 1200 m 1200 m Unlimited D Unlimited D Supported controllers ssltlNode count / network 643232Infinite Infinite Determinism s t s s l Tools support s l t t l Maturity s s s l l Futurelllsss = Good, l = Neutral, t = LowA Data rates and distances for Modbus RTU and PROFIBUS are based on single segments, without using repeaters.B Maximum speeds shown are cable-length dependent. Example: PROFIBUS is 12 Mbit/s at a cable length of 100 m. At 1200 m cable length, PROFIBUS is capable of only 9600 kbit/s.C Maximum cable lengths shown are speed dependent. Example: DeviceNet can run 500 m at 125 kbit/s. If the speed is 500 kbit/s, the cable length is limited to 100 m.D The maximum cable distance between any two nodes on Ethernet is 100 m; however, the number of nodes is unlimited.C441 communication card offeringProtocolCatalog numberInput signal typeDesigned for use with …General purpose I/O 1Mounting optionsC441S611C440S811+nn 2nnStandalone—DIN/panelA C441 standalone communication modules can be used as general purpose I/O.

TP = TEST PIN (DO NOT CONNECT) Figure 2. 8-Lead MSOP (RM-Suffix)GENERAL DESCRIPTIONThe ADR44x series is a family of XFET voltage references featuring ultralow noise, high accuracy, and low temperature drift performance. Using Analog Devices, Inc., patented temperature drift curvature correction and XFET (eXtra implanted junction FET) technology, voltage change vs. temperature nonlinearity in the ADR44x is greatly minimized. The XFET references offer better noise performance than buried Zener references, and XFET references operate offlow supply voltage headroom (0.5 V). This combination of features makes the ADR44x family ideally suited for precision signal conversion applications in high-end data acquisition systems, optical networks, and medical applications.The ADR44x family has the capability to source up to 10 mA of output current and sink up to 5 mA. It also comes with a trim terminal to adjust the output voltage over a 0.5% range without compromising performance. Offered in two electrical grades, the ADR44x family is avail-able in 8-lead MSOP and narrow SOIC packages. All versions are specified over the extended industrial temperature range of −40°C to +125°C.Table 1.

Ripple Rejection Ratio vs. FrequencyADR440/ADR441/ADR443/ADR444/ADR445THEORY OF OPERATIONThe ADR44x series of references uses a new reference generation technique known as XFET (eXtra implanted junction FET). This technique yields a reference with low dropout, good thermal hysteresis, and exceptionally low noise. The core of the XFET reference consists of two junction field-effect transistors (JFETs), one of which has an extra channel implant to raise its pinch-off voltage. By running the two JFETs at the same drain current, the difference in pinch-off voltage can be amplified and used to form a highly stable voltage reference.The intrinsic reference voltage is around 0.5 V with a negative temperature coefficient of about –120 ppm/°C. This slope isessentially constant to the dielectric constant of silicon, and it can be closely compensated for by adding a correction term generated in the same fashion as the proportional-to-temperature (PTAT) term used to compensate band gap references. The advantage of an XFET reference is its correction term, which is approx-imately 20 times lower and requires less correction than that of a band gap reference. Because most of the noise of a band gap reference comes from the temperature compensation circuitry, the XFET results in much lower noise.Figure 33 shows the basic topology of the ADR44x series. The temperature correction term is provided by a current source with a value designed to be proportional to absolute temperature. The general equation is()PTAT P OUT I R1V G V ×−=Δ (1) where:G is the gain of the reciprocal of the divider ratio.ΔV P is the difference in pinch-off voltage between the two JFETs. I PTAT is the positive temperature coefficient correction current. ADR44x devices are created by on-chip adjustment of R2 and R3 to achieve the different voltage option at the reference output.I PTATOUT P PTAT INOUT05428-033Figure 33. Simplified Schematic DevicePOWER DISSIPATION CONSIDERATIONSThe ADR44x family of references is guaranteed to deliver load currents to 10 mA with an input voltage that ranges from 3 V to 18 V . When these devices are used in applications at higher currents, users should use the following equation to account for the temperature effects of increases in power dissipation:A JA D J T P T +θ×= (2) where:T J and T A are the junction and ambient temperatures, respectively.P D is the device power dissipation.θJA is the device package thermal resistance.BASIC VOLTAGE REFERENCE CONNECTIONSThe ADR44x family requires a 0.1 μF capacitor on the input and the output for stability. While not required for operation, a 10 μF capacitor at the input can help with line voltage transient performance.NOTES1. NC = NO CONNECT2. TP = TEST PIN (DO NOT CONNECT)05428-034VFigure 34. Basic Voltage Reference ConfigurationNOISE PERFORMANCEThe noise generated by the ADR44x family of references is typically less than 1.4 μV p-p over the 0.1 Hz to 10.0 Hz band for ADR440, ADR441, and ADR443. Figure 26 shows the 0.1 Hz to 10 Hz noise of the ADR441, which is only 1.2 μV p-p. The noise measurement is made with a band-pass filter made of a 2pole high-pass filter with a corner frequency at 0.1 Hz and a 2pole low-pass filter with a corner frequency at 10.0 Hz.TURN-ON TIMEUpon application of power (cold start), the time required for the output voltage to reach its final value within a specified error band is defined as the turn-on settling time . Two compo-nents normally associated with this are the time for the active circuits to settle and the time for the thermal gradients on the chip to stabilize. Figure 20 and Figure 21 show the turn-on and turn-off settling times for the ADR441.ADR440/ADR441/ADR443/ADR444/ADR445APPLICATIONSOUTPUT ADJUSTMENTThe ADR44x family features a TRIM pin that allows the user to adjust the output voltage of the part over a limited range. This allows errors from the reference and overall system errors to be trimmed out by connecting a potentiometer between the output and the ground, with the wiper connected to the TRIM pin. Figure 35 shows the optimal trim configuration. R1 allows fine adjustment of the output and is not always required. R P should be sufficiently large so that the maximum output current from the ADR44x is not exceeded.V O = ±0.5%05428-035Figure 35. ADR44x Trim FunctionUsing the trim function has a negligible effect on the temperature performance of the ADR44x. However, all resistors need to be low temperature coefficient resistors, or errors can occur.BIPOLAR OUTPUTSBy connecting the output of the ADR44x to the invertingterminal of an operational amplifier, it is possible to obtain both positive and negative reference voltages. Care must be taken when choosing Resistor R1 and Resistor R2 (see Figure 36). They must be matched as closely as possible to ensure minimal differences between the negative and positive outputs. In addition, care must be taken to ensure performance over temperature. Use low temperature coefficient resistors if the circuit is used over temperature; otherwise, differences exist between the two outputs.–5V05428-036Figure 36. ADR44x Bipolar OutputsNEGATIVE REFERENCEFigure 37 shows how to connect the ADR44x and a standard operational amplifier, such as the OP1177, to provide negative voltage. This configuration provides two main advantages. First, it only requires two devices; therefore, it does not require excessive board space. Second, and more importantly, it does not require any external resistors. This means the performance of this circuit does not rely on choosing low temperature coefficient resistors to ensure accuracy.REF05428-037Figure 37. ADR44x Negative ReferenceV OUT is at virtual ground, and the negative reference is taken directly from the output of the operational amplifier. If the negative supply voltage is close to the reference output, the operational amplifier must be dual supply and have low offset and rail-to-rail capability.ADR440/ADR441/ADR443/ADR444/ADR445PROGRAMMABLE VOLTAGE SOURCETo obtain different voltages than those offered by the ADR44x, some extra components are needed. In Figure 38, two potentiometers are used to set the desired voltage, while the buffering amplifier provides current drive. The potentiometer connected between V OUT and GND, with its wiper connected to the noninverting input of the operational amplifier, takes care of coarse trim. The second potentiometer, with its wiperconnected to the trim terminal of the ADR44x, is used for fine adjustment. Resolution depends on the end-to-end resistance value and the resolution of the selected potentiometer.REF05428-038Figure 38. Programmable Voltage SourceFor a completely programmable solution, replace the two potentiometers in Figure 38 with one Analog Devices dual digital potentiometer, offered with either an SPI® or an I 2C® interface. These interfaces set the position of the wiper on both potentiometers and allow the output voltage to be set. Table 9 lists compatible Analog Devices digital potentiometers. Table 9.

Choose feedback resistors to minimize errors over temperature.PROGRAMMABLE CURRENT SOURCEIt is possible to build a programmable current source using a setup similar to the programmable voltage source, as shown in Figure 39. The constant voltage on the gate of the transistor sets the current through the load. Varying the voltage on the gate changes the current. This circuit does not require a dual digital potentiometer.05428-039Figure 39.
