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 CD4046 except that the Zener diode of the metal gate CMOS device has been replaced with a third phase comparator. Phase Comparator I is an exclusive OR (XOR) gate. It pro- vides a digital error signal that maintains a 90 phase 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 rejection. Phase comparator III is an SR flip-flop gate. It can be used to provide the phase comparator functions and is similar to the first comparator in performance. Phase comparator II is an edge sensitive digital sequential network. Two signal outputs are provided, a comparator output and a phase pulse output. The comparator output is a 3-STATE output that provides a signal that locks the VCO output signal to the input signal with 0 phase shift between them. This comparator is more susceptible to noise throw- ing the loop out of lock, but is less likely to lock onto har- monics than the other two comparators. In 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, R1 and R2 pins. An inhibit pin is provided to disable the VCO and the source follower, providing a method of putting the IC in a low power state. The source follower is a MOS transistor whose gate is con- nected to the VCO input and whose drain connects the Demodulator output. This output normally is used by tying a resistor from pin 10 to ground, and provides a means of looking at the VCO input without loading down modifying the characteristics of the PLL filter. Features ■Low dynamic power consumption: (VCC = 4.5V) ■Maximum VCO operating frequency: 12 MHz (VCC = 4.5V) ■Fast comparator response time (VCC = 4.5V) Comparator I: 25 ns Comparator II: 30 ns Comparator III: 25 ns ■VCO has high linearity and high temperature stability Ordering Code: Devices also available in Tape and Reel.

DC Electrical Characteristics (Note 4) Note 4: For a power supply of 5V ± 10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage cur- rent (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.

www.fairchildsemi.com 8 M M 7 4 H C 4 0 4 6 Detailed Circuit Description VOLTAGE CONTROLLED OSCILLATOR/SOURCE FOLLOWER The VCO requires two or three external components to operate. These are R1, R2, C1. Resistor R1 and capacitor C1 are selected to determine the center frequency of the VCO. R1 controls the lock range. As R1’s resistance decreases the range of fMIN to fMAX increases. Thus the VCO’s gain increases. As C1 is changed the offset (if used) of R2, and the center frequency is changed. (See typical performance curves) R2 can be used to set the offset fre- quency with 0V at VCO input. If R2 is omitted the VCO range is from 0Hz. As R2 is decreased the offset frequency is increased. The effect of R2 is shown in the design infor- mation table and typical performance curves. By increasing the value of R2 the lock range of the PLL is offset above 0Hz and the gain (Hz/Volt) does not change. In general, when offset is desired, R2 and C1 should be chosen first, and then R1 should be chosen to obtain the proper center frequency. Internally the resistors set a current in a current mirror as shown in Figure 1. The mirrored current drives one side of 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 pin 4. VCO WITHOUT OFFSET R2 = ∞ VCO WITH OFFSET FIGURE 1.

Logic Diagram for VCO The 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 connecting a resistor to ground and its drain output will follow the VCO input signal. An 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 follower. The 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 either directly feed the comparator input of the phase com- parators or feed external prescalers (counters) to enable frequency synthesis. PHASE COMPARATORS All 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 74HC. The Comparator input is a standard digital input. Both input structures are shown in Figure 3. The outputs of these comparators are essentially standard 74HC voltage outputs. (Comparator II is 3-STATE.) FIGURE 3. Logic Diagram for Phase Comparator I and the common input circuit for all three comparators
