In addition to the typical outputs provided by standard 100-MHz 440BX FTGs,the W144 adds a thirteen output buffer, supporting SDRAM DIMM modules in conjunction with the chipset.Cypress ’s proprietary spread spectrum frequency synthesis technique is a feature of the CPU and PCI outputs. When en-abled, this feature reduces the peak EMI measurements of not only the output signals and their harmonics, but also of any other clock signals that are properly synchronized to them.Functional DescriptionI/O Pin OperationPins 7, 8, 25, 26, and 46 are dual-purpose l/O pins. Upon pow-er-up these pins act as logic inputs, allowing the determination of assigned device functions. A short time after power-up, the logic state of each pin is latched and the pins become clock outputs. This feature reduces device pin count by combining clock outputs with input select pins.An external 10-k Ω “strapping ” resistor is connected between the l/O pin and ground or V DD . Connection to ground sets a latch to “0,” connection to V DD sets a latch to “1.” Figure 1 and Figure 2 show two suggested methods for strapping resistor connections.Upon W144 power up, the first 2 ms of operation is used for input logic selection. During this period, the five I/O pins (7, 8,25, 26, 46) are three-stated, allowing the output strapping re-sistor on the l/O pins to pull the pin and their associated ca-pacitive clock load to either a logic HIGH or LOW state. At the end of the 2ms period, the established logic “0” or “1” condition of the l/O pin is latched. Next the output buffer is enabled con-verting the l/O pins into operating clock outputs. The 2-ms tim-er starts when VDD reaches 2.0V . The input bits can only be reset by turning VDD off and then back on again.It should be noted that the strapping resistors have no signifi-cant effect on clock output signal integrity. The drive imped-ance of clock outputs are <40Ω (nominal) which is minimally affected by the 10-k Ω strap to ground or V DD . As with the se-ries termination resistor, the output strapping resistor should be placed as close to the l/O pin as possible in order to keep the interconnecting trace short. The trace from the resistor to ground or V DD should be kept less than two inches in length to prevent system noise coupling during input logic sampling.When the clock outputs are enabled following the 2-ms input period, the specified output frequency is delivered on the pin,assuming that V DD has stabilized. If V DD has not yet reached full value, output frequency initially may be below target but will increase to target once V DD voltage has stabilized. In either case, a short output clock cycle may be produced from the CPU clock outputs when the outputs are enabled.Power-on Reset TimerOutput Three-stateData LatchHold QDW144V DDClock Load10 k ΩOutput Buffer(Load Option 1)10 k Ω(Load Option 0)Output LowOutput Strapping R esistor Series Term ination ResistorFigure 1.Input Logic Selection Through Resistor Load OptionPower-on Reset TimerOutput Three-stateData LatchHold QDW144V DDClock LoadR10 k ΩOutput BufferOutput LowOutput Strapping Resistor Series Termination Resistor Jumper OptionsResistor Value RFigure 2.Input Logic Selection Through Jumper OptionSpread Spectrum FeatureThe device generates a clock that is frequency modulated in order to increase the bandwidth that it occupies. By increasing the bandwidth of the fundamental and its harmonics, the am-plitudes of the radiated electromagnetic emissions are re-duced. This effect is depicted in Figure 3.As shown in Figure 3, a harmonic of a modulated clock has a much lower amplitude than that of an unmodulated signal. The reduction in amplitude is dependent on the harmonic number and the frequency deviation or spread. The equation for the reduction isdB = 6.5 + 9*log10(P) + 9*log10(F)Where P is the percentage of deviation and F is the frequency in MHz where the reduction is measured.The output clock is modulated with a waveform depicted in Figure 4. This waveform, as discussed in “Spread Spectrum Clock Generation for the Reduction of Radiated Emissions ” by Bush, Fessler, and Hardin produces the maximum reduction in the amplitude of radiated electromagnetic emissions. The deviation selected for this chip is specified in Table 7. Figure 4details the Cypress spreading pattern. Cypress does offer op-tions with more spread and greater EMI reduction. Contact your local Sales representative for details on these devices.Spread Spectrum clocking is activated or deactivated by se-lecting the appropriate values for bits 1–0 in data byte 0 of the I 2C data stream.

Upon power-up, the W144 initializes with default register settings, therefore the use of this serial data interface is optional. The serial interface is write-only (to the clock chip) and is the dedicated function of device pins SDAT A and SCLOCK. In motherboard applications, SDA TA and SCLOCK are typically driven by two logic outputs of the chipset. Clock device register changes are normally made upon system initialization, if any are required. The interface can also be used during system operation for power manage-ment functions. T able 3 summarizes the control functions of the serial data interface. OperationData is written to the W144 in eleven bytes of eight bits each.Bytes are written in the order shown in T able 4.Table 3.Serial Data Interface Control Functions SummaryControl Function DescriptionCommon ApplicationClock Output DisableAny individual clock output(s) can be disabled. Disabled outputs are actively held LOW.Unused outputs are disabled to reduce EMI and system power.

Since other devices may exist on the same com-mon serial data bus, it is necessary to have a specific slave address for each potential receiver. The slave receiver address for the W144 is 11010010. Register setting will not be made if the Slave Address is not correct (or is for an alternate slave receiver).2Command Code Don ’t CareUnused by the W144, therefore bit values are ignored (“don ’t care ”). This byte must be included in the data write sequence to maintain proper byte allocation. The Command Code Byte is part of the standard serial communication protocol and may be used when writing to anoth-er addressed slave receiver on the serial data bus.3Byte Count Don ’t CareUnused by the W144, therefore bit values are ignored (“don ’t care ”). This byte must be included in the data write sequence to maintain proper byte allocation. The Byte Count Byte is part of the standard serial communication protocol and may be used when writing to anoth-er addressed slave receiver on the serial data bus.4Data Byte 0Refer to Table 5The data bits in Data Bytes 0–7 set internal W144 registers that control device operation. The data bits are only accepted when the Address Byte bit sequence is 11010010, as noted above.

Photo-DiodeCurrent-to-Voltage ConvertersConverting the small output current of a photo-diode trans-ducer to a fast responding voltage is often challenging.Here are some ways to use high-speed Current Feedback and Voltage Feedback op amps to do the jobCurrent Feedback Amplifier SolutionCurrent Feedback Amplifiers (CFA)are especially suited to implement this function,as shown in Figure 1.With an effective internal buffer on the inverting node of the op amp,the output impedance R O (internal to U1,not shown)and the photo-diode’s output capacitance C IN (typically 10-200pF)introduce a zero in the noise gain at approximately 1/2πx (R O x C IN ).In comparison,the zero produced by a Voltage Feedback op amp in a similar configuration [1/2πx (R IN ||R F ||R BIAS )x C IN ]tends to be much lower in frequencyand more troublesome.This being the case,C IN has less of an effect on reduction of the converter bandwidth,and achieving stability is easier when using a CFA.If C IN is sufficiently large,the closed loop phase shift will approach –180˚at the cross-over frequency (where open loop transimpedance gain crosses the noise gain function).As with Voltage Feedback Amplifiers,the closed loop ampli-fier can be compensated by adding a small capacitor (C F )across R F .In the case of Figure 1,using the CLC450CFA,C F was experimentally determined to be around 2pF for about 10%overshoot in the step response.C F improves stability by counteracting the effect of the zero discussed in the paragraph above by introducing a low frequency pole (1/2πx R F x C F )and an inconsequential zero (1/2πx R O x C F ).It is possible to change the required 2pF compensation capacitor to a more practical value,by adding R A and R B in a voltage divider,as shown in Figure 2.The new value of C'f is (1+R B /R A )x C F .This relationship holds true as long as R B <<R F .For this example,select R A =50Ω,and R B =500Ω.There-fore,C'f =(1+500/50)x2pF =~22pF which is a much more practical component value.This value needs to be ’fine tuned’in the real application for proper step response.20050001FIGURE 1.Single-Supply Photo-Diode Amplifier Using CLC450Current-Feedback AmplifierNational Semiconductor Application Note 1244Hooman Hashemi September 2002Photo-Diode Current-to-Voltage ConvertersAN-1244©2002National Semiconductor Corporation Current Feedback Amplifier Solution (Continued)Voltage Feedback Amplifier SolutionIt’s more difficult to design a good current-to-voltage con-verter using a Voltage Feedback Amplifier (VFA).As dis-cussed above,phase shift caused by photo-diode capaci-tance is often a source of instability.Furthermore,wide bandwidth usually comes at the expense of supply currents and higher supply voltage.However,the new LMH6642high-speed low-voltage VFA op amp has excellent perfor-mance in a transimpedance gain block,as shown in Figure 3.This device can operate down to 2.7V single supply and its −3dB BW (A V =+1)is more than 100MHz (with a supply current of only 2.7mA)!Because of the ’Dielectric Isolation’process this device is based on,the traditional supply volt-age vs.speed trade-off has been alleviated to a great extent allowing low power consumption and operation at lower supply voltages.In addition,the device has Rail-to-Rail out-put swing capability to maximize the output swing,and is capable of driving ±50mA into the load.With 5V single supply,the device common mode voltage is shifted to near half-supply using R 10-R 11as a voltage divider from V CC .The common-base transistor stage (Q1)isolates the photo-diode’s capacitance from the inverting terminal,allowing wider bandwidth and easing the compensation re-quired.Note that the collector of Q1does not have any voltage swing,so the Miller effect is minimized.The diode on the base of Q1is for temperature compensation of its bias point.Q1bias current was set to be large enough to handle the peak-to-peak photo-diode excitation,yet not too large as to shift the U1output too far from mid-supply.The overall circuit draws about 4.5mA from the +5V power supply and achieves about 35MHz of closed loop bandwidth @1V PP .Figure 4shows the output large signal step response.C F can be increased to reduce the overshoot,at the expense of bandwidth.20050002FIGURE 2.R A -R B Resistor Divider Allows Use ofPractical Value for C'f20050003FIGURE

LM124A/LM124QMLLow Power Quad Operational AmplifiersGeneral DescriptionThe LM124/124A consists of four independent,high gain,internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages.Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.Application areas include transducer amplifiers,DC gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems.For example,the LM124/124A can be directly op-erated off of the standard +5Vdc power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional +15Vdc power supplies.Unique Characteristicsn In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground,even though operated from only a single power supply voltagen The unity gain cross frequency is temperature compensatedn The input bias current is also temperature compensatedAdvantagesn Eliminates need for dual suppliesn Four internally compensated op amps in a single packagen Allows directly sensing near GND and V OUT also goes to GNDn Compatible with all forms of logicn Power drain suitable for battery operationFeaturesn Internally frequency compensated for unity gain n Large DC voltage gain 100dBn Wide bandwidth (unity gain)1MHz (temperature compensated)n Wide power supply range:Single supply 3V to 32Vor dual supplies ±1.5V to ±16Vn Very low supply current drain (700µA)—essentially independent of supply voltage n Low input biasing current 45nA (temperature compensated)n Low input offset voltage 2mV and offset current:5nAn Input common-mode voltage range includes ground n Differential input voltage range equal to the power supply voltagen Large output voltage swing 0V

damage to the device may occur.Operating Ratings indicate conditions for which the device is functional,but do not guarantee specific performance limits.For guaranteed specifications and test conditions,see the Electrical Characteristics.The guaranteed specifications apply only for the test conditions listed.Some performance characteristics may degrade when the device is not operated under the listed test conditions.Note 2:The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature),ThetaJA (package junction to ambient thermal resistance),and TA (ambient temperature).The maximum allowable power dissipation at any temperature is Pdmax =(Tjmax -TA)/ThetaJA or the number given in the Absolute Maximum Ratings,whichever is lower.Note 3:Short circuits from the output to V+can cause excessive heating and eventual destruction.When considering short circuits to ground,the maximum output current is approximately 40mA independent of the magnitude of V+.At values of supply voltage in excess of +15Vdc,continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction.Destructive dissipation can result from simultaneous shorts on all amplifiers.Note 4:This input current will only exist when the voltage at any of the input leads is driven negative.It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps.In addition to this diode action,there is also lateral NPN parasitic transistor

negative.This is not destructive and normal output states will re-establish when the input voltage,which was negative,again returns to a value greater than -0.3Vdc (at 25C).Note 5:Human body

Limiting2010804420108045LM124A/LM124QMLApplication HintsThe LM124series are op amps which operate with only a single power supply voltage,have true-differential inputs,and remain in the linear mode with an input common-mode voltage of 0V DC .These amplifiers operate over a wide range of power supply voltage with little change in performance characteristics.At 25˚C amplifier operation is possible down to a minimum supply voltage of 2.3V DC .The pinouts of the package have been designed to simplify PC board layouts.Inverting inputs are adjacent to outputs for all of the amplifiers and the outputs have also been placed at the corners of the package (pins 1,7,8,and 14).Precautions should be taken to insure that the power supply for the integrated circuit never becomes reversed in polarity or that the unit is not inadvertently installed backwards in a test socket as an unlimited current surge through the result-ing forward diode within the IC could cause fusing of the internal conductors and result in a destroyed unit.Large differential input voltages can be easily accommo-dated and,as input differential voltage protection diodes are not needed,no large input currents result from large differ-ential input voltages.The differential input voltage may be larger than V +without damaging the device.Protection should be provided to prevent the input voltages from going negative more than −0.3V DC (at 25˚C).An input clamp diode with a resistor to the IC input terminal can be used.To reduce the power supply drain,the amplifiers have a class A output stage for small signal levels which converts to class B in a large signal mode.This allows the amplifiers to both source and sink large output currents.Therefore both NPN and PNP external current boost transistors can be used to extend the power capability of the basic amplifiers.The output voltage needs to raise approximately 1diode drop above ground to bias the on-chip vertical PNP transistor for output current sinking applications.For ac applications,where the load is capacitively coupled to the output of the amplifier,a resistor should be used,from the output of the amplifier to ground to increase the class A bias current and prevent crossover distortion.Where the load is directly coupled,as in dc applications,there is no crossover distortion.Capacitive loads which are applied directly to the output of the amplifier reduce the loop stability margin.Values of 50pF can be accommodated using the worst-case non-inverting unity gain rge closed loop gains or resistive isolation should be used if larger load capacitance must be driven by the amplifier.The bias network of the LM124establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 3V DC to 30V DC .Output short circuits either to ground or to the positive power supply should be of short time duration.Units can be de-stroyed,not as a result of the short circuit current causing metal fusing,but rather due to the large increase in IC chip dissipation which will cause eventual failure due to exces-sive junction temperatures.Putting direct short-circuits on more than one amplifier at a time will increase the total IC power dissipation to destructive levels,if not properly pro-tected with external dissipation limiting resistors in series with the output leads of the amplifiers.The larger value of output source current which is available at 25˚C provides a larger output current capability at elevated temperatures (see typical performance characteristics)than a standard IC op amp.The circuits presented in the section on typical applications emphasize operation on only a single power supply voltage.If complementary power supplies are available,all of the standard op amp circuits can be used.In general,introduc-ing a pseudo-ground (a bias voltage reference of V +/2)will allow operation above and below this value in single power supply systems.Many application circuits are shown which take advantage of the wide input common-mode voltage range which includes ground.In most cases,input biasing is not required and input voltages which range to ground can easily be accommodated.L M 124A /L M 124Q M LTypical Single-Supply Applications(V+=5.0V DC)Non-Inverting DC Gain(0V Input=0V Output)20108005 *R not needed due to temperature independent I

If required, custom versions of the actuator can be ordered. The parameters are variable and can be changed by three means: Factory pre-set or custom configuration, set by the customer using PC-Tool software or the handheld ZTH US.For fail-safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. A feedback signal is provided for position indication for primary and secondary applications. Two AF's can be piggybacked for torque loads to max. 360 in-lb. Minimum 3/4" diameter shaft. OR Maximum of three AF's can be piggybacked for torque loads to max. 432 in-lb. Minimum 3/4" diameter shaft. Primary and secondary wiring for either configuration. Actuators must be mechanically linked.When not mechanically linked, actuators must be wired in parallel.The AF..24-MFT N4 actuator provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator will synchronize the 0° mechanical stop or the physical damper or valve mechanical stop and use this point for its zero position during normal control operations. A unique manual override allows the setting of any actuator position within its 95° of rotation with no power applied. This mechanism can be released physically by the use of a crank supplied with the actuator. When power is applied the manual override is released and the actuator drives toward the fail-safe position. The actuator uses a brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuators's exact position. The ASIC monitors and controls the brushless DC motor's rotation and provides a Digital Rotation Sensing (DRS) function to prevent damage to the actuator in a stall condition. The position feedback signal is generated without the need for mechanical feedback potentiometers using DRS. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. The AF..24-MFT N4 is mounted directly to control shafts up to 1.05" diameter by means of its universal clamp and anti-rotation bracket. The spring return system provides minimum specified torque to the application during a power interruption. The AF..24-MFT N4 actuator is shipped at 5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off.Installation Note: Use suitable flexible metallic conduit or its equivalent with the conduit fitting. Not suitable for plenum applications.For low ambient temperatures, the optional supplemental (-Y) Heater add-on is available.Typical specification Factory settings Spring return control damper actuators shall be direct coupled type which require no crank armand linkage and be capable of direct mounting to a jackshaft up to a 1.05” diameter. Theactuator must provide modulating damper control in response to a 2 to 10 VDC or, with the addition of a 500Ω resistor, a 4 to 20 mA control input from an electronic controller orpositioner. The actuators must be designed so that they may be used for either clockwise orcounter clockwise fail-safe operation. Actuators shall use a brushless DC motor controlled by a microprocessor and be protected from overload at all angles of rotation. Run time shall be constant, and independent of torque. A 2 to 10 VDC feedback signal shall be provided for position feedback or primary and secondary applications. Actuators with auxiliary switches must be constructed to meet the requirements for Double Insulation so an electrical ground is not required to meet agency listings. Actuators shall be cULus listed and have a 5 year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo.Default parameters for 2 to 10 VDC applications of the AF..-MFT actuator are assigned during manufacturing. If required, custom versions of the actuator can be ordered.
