74VHC4046中文资料TL F 1167574VHC4046CMOS Phase Lock LoopOctober 199574VHC4046CMOS Phase Lock LoopGeneral DescriptionThe 74VHC4046is a low power phase lock loop utilizing advanced silicon-gate CMOS technology to obtain high fre-quency operation both in the phase comparator and VCO sections This device contains a low power linear voltage controlled oscillator (VCO) a source follower and three phase comparators The three phase comparators have a common signal input and a common comparator input The signal input has a self biasing amplifier allowing signals to be either capacitively coupled to the phase comparators with a small signal or directly coupled with standard input logic levels This device is similar to the CD4046except that the Zener diode of the metal gate CMOS device has been replaced with a third phase comparatorPhase Comparator I is an exclusive OR (XOR)gate It pro-vides a digital error signal that maintains a 90phase shift between the VCO’s center frequency and the input signal (50%duty cycle input waveforms) This phase detector is more susceptible to locking onto harmonics of the input fre-quency than phase comparator I but provides better noise rejectionPhase comparator III is an SR flip-flop gate It can be used toprovide the phase comparator functions and is similar to the first comparator in performancePhase comparator II is an edge sensitive digital sequential network Two signal outputs are provided a comparator out-put and a phase pulse output The comparator output is a TRI-STATE output that provides a signal that locks the VCO output signal to the input signal with 0phase shift be-tween them This comparator is more susceptible to noise throwing the loop out of lock but is less likely to lock onto harmonics than the other two comparatorsIn a typical application any one of the three comparators feed an external filter network which in turn feeds the VCO input This input is a very high impedance CMOS input which also drives the source follower The VCO’s operating frequency is set by three external components connected to the C1A C1B R1and R2pins An inhibit pin is provided to disable the VCO and the source follower providing a meth-od of putting the IC in a low power stateThe source follower is a MOS transistor whose gate is con-nected to the VCO input and whose drain connects the De-modulator output This output normally is used by tying a resistor from pin 10to ground and provides a means of looking at the VCO input without loading down modifying the characteristics of the PLL filterFeaturesY Low dynamic power

R2 C1 Resistor R1and capacitor C1 are selected to determine the center frequency of the VCO R1controls the lock range As R1’s resistance decreases the range of f min to f max increases Thus the VCO’s gain decreases As C1is changed the offset(if used)of R2 and the center frequency is changed (See typical performance curves)R2can be used to set the offset frequency with0V at VCO input If R2is omitted the VCO range is from0Hz As R2is decreased the offset frequency is increased The ef-fect of R2is shown in the design information table and typi-cal performance curves By increasing the value of R2the lock rangeof the PLL is offset above0Hz and the gain (Volts rad )does not change In general when offset is de-sired R2and C1should be chosen first and then R1should be chosen to obtain the proper center frequency Internally the resistors set a current in a current mirror as shown in Figure1 The mirrored current drives one side ofTL F 11675–18FIGURE2 Logic Diagram for VCO8Detailed Circuit Description (Continued)the capacitor once the capacitor charges up to the thresh-old of the schmitt trigger the oscillator logic flips the capaci-tor over and causes the mirror to charge the opposite side of the capacitor The output from the internal logic is then taken to pin4The input to the VCO is a very high impedance CMOS input and so it will not load down the loop filter easing the filters design In order to make signals at the VCO input accessible without degrading the loop performance a source follower transistor is provided This transistor can be used by con-necting a resistor to ground and its drain output will follow the VCO input signalAn inhibit signal is provided to allow disabling of the VCO and the source follower This is useful if the internal VCO is not being used A logic high on inhibit disables the VCO and source followerThe output of the VCO is a standard high speed CMOS output with an equivalent LSTTL fanout of 10 The VCO output is approximately a square wave This output can ei-ther directly feed the comparator input of the phase compar-ators or feed external prescalers (counters)to enable fre-quency synthesis PHASE COMPARATORSAll three phase comparators share two inputs Signal In and Comparator In The Signal In has a special DC bias network that enables AC coupling of input signals If the signals are not AC coupled then this input requires logic levels the same as standard 74VHC The Comparator input is a stan-dard digital input Both input structures are shown in Figure 3The outputs of these comparators are essentially standard 74VHC voltage outputs (Comparator II is TRI-STATE )TL F 11675-19FIGURE 3 Logic Diagram for Phase Comparator I and the Common Input Circuit for All Three ComparatorsTL F 11675–20FIGURE 4 Typical Phase Comparator I Waveforms9Detailed Circuit Description(Continued)Thus in normal operation V CC and ground voltage levels are fed to the loop filter This differs from some phase detectors which supply a current output to the loop filter and this should be considered in the design (The CD4046also pro-vides a voltage ) Figure5shows the state tables for all three comparators PHASE COMPARATOR IThis comparator is a simple XOR gate similar to the 54 74HC86 and its operation is similar to an overdriven balanced modulator To maximize lock range the input fre-quencies musthave a50%duty cycle Typical input and output waveforms are shown in Figure4 The output of the phase detector feeds the loop filter which averages the out-put voltage The frequency range upon which the PLL will lock onto if initially out of lock is defined as the capture range The capture range for phase detector I is dependent on the loop filter employed The capture range can be as large as the lock range which is equal to the VCO frequency rangeTo see how the detector operates refer to Figure4 When two square wave inputs are applied to this comparator an output waveform whose duty cycle is dependent on the phase difference between the two signals results As the phase difference increases the output duty cycle increases and the voltage after the loop filter increases Thus in order to achieve lock when the PLL input frequency increases the VCO input voltage must increase and the phase difference between comparator in and signal in will increase At an input frequency equal f min the VCO input is at0V and this requires the phase detector output to be ground hence the two input signals must be in phase When the input frequen-cy is f max then the VCO input must be V CC and the phase detector inputs must be180 out of phaseThe XOR is more susceptible to locking onto harmonics of the signal input than the digital phase detector II This can be seen by noticing that a signal2times the VCO frequency results in the same output duty cycle as a signal equal the VCO frequency The difference is that the output frequency of the2f example is twice that of the other example The loop filter and the VCO range should be designed to prevent locking on to harmonics PHASE COMPARATOR IIThis detector is a digital memory network It consists of fourflip-flops and some gating logic a three state output and a phase pulse output as shown in Figure6 This comparator acts only on the positive edges of the input signals and is thus independent of signal duty cyclePhase comparator II operates in such a way as to force the PLL into lock with0phase difference between the VCO output and the signal input positive waveform edges Figure 7shows some typical loop waveforms First assume that the signal input phase is leading the comparator input ThisPhase Comparator State DiagramsTL F 11675–21FIGURE5 PLL State Tables10Detailed Circuit Description(Continued)TL F 11675–22FIGURE6 Logic Diagram for Phase Comparator IITL F 11675–23FIGURE7 Typical Phase Comparator II Output Waveforms11Detailed Circuit Description (Continued)means that the VCO’s frequency must be increased to bring its leading edge into proper phase alignment Thus the phase detector II output is set high This will cause the loop filter to charge up the VCO input increasing the VCO fre-quency Once the leading edge of the comparator input is detected the output goes TRI-STATE holding the VCO input at the loop filter voltage If the VCO still lags the signal then the phase detector will again charge up to VCO input for the time between the leading edges of both waveformsIf the VCO leads the signal then when the leading edge of the VCO is seen the output of the phase comparator goes low This discharges the loop filter until the leading edge of the signal is detected at which time the output TRI-STATE itself again This has the effect of slowing down the VCO to again make the rising edges of both waveform coincident When the PLL is out of lock the VCO will be running either slower or faster than the signal input If it is running slower the phase detector will see more signal rising edges and so the output of the phase comparator will be high a majority of the time raising the VCO’s frequency Conversely if the VCO is running faster than the signal the output of the de-tector will be low most of the time and the VCO’s output frequency will be decreasedAs one can see when the PLL is locked the output of phase comparator II will be almost always TRI-STATE except for minor corrections at the leading edge of the waveforms When the detector is TRI-STATE the phase pulse output is high This outputcan be used to determine when the PLL is in the locked condition This detector has several interesting characteristics Over the entire VCO frequency range there is no phase differ-ence between the comparator input and the signal input The lock range of the PLL is the same as the capture rangeMinimal power is consumed in the loop filter since in lock the detector output is a high impedance Also when no sig-nal is present the detector will see only VCO leading edges and so the comparator output will stay low forcing the VCO to f min operating frequencyPhase comparator II is more susceptible to noise causing the phase lock loop to unlock If a noise pulse is seen on the signal input the comparator treats it as another positive edge of the signal and will cause the output to go high until the VCO leading edge is seen potentially for a whole signal input period This would cause the VCO to speed up during that time When using the phase comparator I the output of that phase detector would be disturbed for only the short duration of the noise spike and would cause less upset PHASE COMPARATOR IIIThis comparator is a simple S-R Flip-Flop which can func-tion as a phase comparator Figure 8 It has some similar characteristics to the edge sensitive comparator To see how this detector works assume input pulses are applied to the signal and comparator inputs as shown in Figure 9 When the signal input leads the comparator input the flop is set This will charge up the loop filter and cause the VCO to speed up bringing the comparator into phase with the sig-nal input When using short pulses as input this comparator behaves very similar to the second comparator But one can see that if the signal input is a long pulse the output of the comparator will be forced to a one no matter how manycomparator input pulses are received Also if the VCO input is a square wave (as it is)and the signal input is pulse then the VCO will force the comparator output low much of the time Therefore it is ideal to condition the signal and com-parator input to short pulses This is most easily done by using a series

It is specified in compliance with JEDEC standard no. 7A.The 74HC4049 provides six inverting buffers with a modified input protection structure, which has no diode connected to V CC . Input voltages of up to 15 V may therefore be used.This feature enables the inverting buffers to be used as logic level translators, which will convert high level logic to low level logic, while operating from a low voltage power supply. For example 15 V logic (“4000B series”) can be converted down to 2 V logic.The actual input switch level remains related to the V CC and is the same as mentioned in the family characteristics.At the same time each part can be used as a simple inverter without level translation.APPLICATIONS•Converting 15 V logic (“4000B” series) down to 2 V logic.QUICK REFERENCE DATAGND =0 V; T amb =25°C; t r =t f =6 nsNote1.C PD is used to determine the dynamic power dissipation (P D in µW):P D =C PD × V CC 2× f i +∑ (C L × V CC 2 ×f o ) where:f i =input frequency in MHz f o =output frequency in MHz C L =output load capacitance in pF V CC =supply voltage in V∑ (C L × V CC 2× f o )=sum of outputs ORDERING INFORMATIONSee “74HC/HCT/HCU/HCMOS Logic Package Information”.SYMBOL PARAMETERCONDITIONS TYPICAL UNITHCt PHL /t PLH propagation delay nA to nY C L =15 pF; V CC =5 V8ns C I input capacitance3.5pF C PD power dissipation capacitance per buffer note 114pFPIN DESCRIPTIONPIN NO.SYMBOL NAME AND FUNCTION1V CC positive supply voltage2, 4, 6, 10, 12, 151Y to 6Y data outputs3, 5, 7, 9, 11, 141A to 6A data inputs8GND ground (0 V)13, 16n.c.not connectedFig.1 Pin configuration.Fig.2 Logic symbol.Fig.3 IEC logic symbol.Fig.4 Functional diagram.Fig.5Input protection for HC4049.

In 3 V and 5 V systems these can achieve high-speed operation with the low power dissipation that is a feature of CMOS.The TC74VHC4051A/4052A/4053A offer analog/digital signal selection as well as mixed signals. The 4051A has an 8-channel configuration, the 4052A has an 4-channel × 2 configuration, and the 4053A has a 2-channel × 3 configuration.The switches for each channel are turned ON by the control pin digital signals.All control inputs are equipped with a newly developed input protection circuit that avoids the need for a diode on the plus side (forward side from the input to the V CC). As a result, for example, 5.5 V signals can be permitted on the inputs even when the power supply voltage to the circuits is off. As a result of this input power protection, the TC74VHC4051A/4052A/4053A can be used in a variety of applications, including in the system which has two power supplies, and in battery backup circuits.Features•Low ON resistance: R on = 45Ω (typ.)

TOSHIBA CMOS Digital Integrated Circuit Silicon MonolithicTC74VHCT14AF,TC74VHCT14AFN,TC74VHCT14AFT,TC74VHCT14AFKHex Schmitt InverterThe TC74VHCT14A is an advanced high speed CMOS SCHMITT INVERTER fabricated with silicon gate C 2MOS technology.It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.Pin configuration and function are the same as theTC74VHC04 but the inputs have hysteresis and with its schmitt trigger function, the TC74VHC14 can be used as a line receivers which will receive slow input signals.The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 to 5 V system.Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: V CC = 0 VFeatures• High speed: t pd = 5.0 ns (typ.) at V CC = 5 V• Low power dissipation: I CC = 2 μA (max) at Ta = 25°C • Compatible with TTL inputs: V IL = 0.8 V (max) V IH = 2.0 V (min)• Power down protection is provided on all inputs and outputs. • Balanced propagation delays: t pLH ∼ − t pHL • Low noise: V OLP =0.8 V (max)•Pin and function compatible with the 74 series(74AC/HC/F/ALS/LS etc.) 14 type.WeightSOP14-P-300-1.27A : 0.18 g (typ.)

© 1999 Fairchild Semiconductor Corporation DS005214February 1984Revised October 1999MM74HC4049 • MM74HC4050 Hex Inverting Logic Level Down Converter • Hex Logic Level Down ConverterMM74HC4049 • MM74HC4050Hex Inverting Logic Level Down Converter • Hex Logic Level Down ConverterGeneral DescriptionThe MM74HC4049 and the MM74HC4050 utilize advanced silicon-gate CMOS technology, and have a mod-ified input protection structure that enables these parts to be used as logic level translators which will convert high level logic to a low level logic while operating from the low logic supply. For example, 0–15V CMOS logic can be con-verted to 0–5V logic when using a 5V supply. The modified input protection has no diode connected to V CC , thus allow-ing the input voltage to exceed the supply. The lower zener diode protects the input from both positive and negative static voltages. In addition each part can be used as a sim-ple buffer or inverter without level translation.

Thus the 4.5V values should be used when designing with this supply. Worst case V IH and V IL occur at V CC = 5.5V and 4.5V respectively. (The V IH value at 5.5V is 3.85V.) The worst case leakage cur-rent (I IN , I CC , I OZ ) occur for CMOS at the higher voltage and so the 6.0V values should be used.Supply Voltage (V CC )−0.5 to +7.0V DC Input Voltage (V IN )−1.5 to +18V DC Output Voltage (V OUT )−0.5 to V CC +0.5VClamp Diode Current (I ZK , I OK )−20 mA DC Output Current, per pin (I OUT )±25 mA DC V CC or GND Current, per pin (I CC )±50 mAStorage Temperature Range (T STG )−65°C to +150°CPower Dissipation (P D )(Note 3)600 mW S.O.

GENERAL DESCRIPTION
The 74HC/HCT7404 are high-speed Si-gate CMOS devices specified in compliance with JEDEC standard no.7A.
The “7404” is an expandable, First-In First-Out (FIFO) memory organized as 64 words by 5 bits. A guaranteed 15 MHz data-rate makes it ideal for high-speed applications. A higher data-rate can be obtained in applications where the status flags are not used (burst-mode).

Note 1:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
They are useful for battery back up circuits, because input voltage can be applied on IC’s which are not biased by VCC.
