6. Functional description

6.1. VCO control

The VCO requires an external capacitor (C1) and resistor (R1) with an optional resistor (R2).

Resistor R1 and capacitor C1 determine the frequency range of the VCO, while resistor R2 enables

the VCO to have a frequency off-set if required. The high input impedance of the VCO simplifies

the design of low-pass filters; it permits the designer a wide choice of resistor/capacitor ranges. In

order not to load the low-pass filter, a source-follower output of the VCO input voltage is provided

at SF_OUT (pin 10). If this is used, a load resistor (R_L) should be connected from SF_OUT to V_SS

if unused, SF_OUT should be left open. The VCO output (pin 4) can either be connected directly

to the comparator input COMP_IN (pin 3) or via a frequency divider. A LOW-level at the inhibit

;

input INH_IN (pin 5) enables the VCO and the source follower, while a HIGH-level turns both off to

minimize standby power consumption.

6.2. Phase comparators

The phase-comparator signal input SIG_IN (pin 14) can be direct-coupled, provided the signal

swing is between the standard HE4000B family input logic levels. The signal must be capacitively

coupled to the self-biasing amplifier at the signal input with smaller swings. Phase comparator 1 is

an EXCLUSIVE-OR network. The signal and comparator input frequencies must have a 50% duty

factor to obtain the maximum lock range. The average output voltage of the phase comparator is

equal to 0.5V_DDwhen there is no signal or noise at the signal input. The average voltage to the

VCO input VCO_IN is supplied by the low-pass filter connected to the output of phase comparator

1. This also causes the VCO to oscillate at the center frequency (f₀). The frequency capture range

(2f_C) is defined as the frequency range of input signals on which the PLL will lock if it was initially

out of lock. The frequency lock range (2f_L) is defined as the frequency range of input signals on

which the loop will stay locked if it was initially in lock. The capture range is smaller or equal to the

lock range.
