Phase-locked loop with VCO

8. Functional description

The 74HC4046A; 74HCT4046A is a phase-locked-loop circuit that comprises a linear

voltage-controlled oscillator (VCO) and three different phase comparators (PC1, PC2 and

PC3). It has a common signal input amplifier and a common comparator input (see

Figure 1).

The signal input can be directly coupled to a large voltage signal, or indirectly

coupled (with a series capacitor) to a small voltage signal. A self-bias input circuit keeps

small voltage signals within the linear region of the input amplifiers. With a passive

low-pass filter, the 74HC4046A; 74HCT4046A forms a second-order loop PLL. The

excellent VCO linearity is achieved by the use of linear op amp techniques.

8.1 VCO

The VCO requires one external capacitor C1 (between pins C1A and C1B) and one

external resistor R1 (between pins R1 and GND). Alternatively, it requires two external

resistors R1 and R2 (between pins R1 and GND, and R2 and GND). Resistor R1 and

capacitor C1 determine the frequency range of the VCO. Resistor R2 enables the VCO to

have a frequency offset if necessary (see

Figure 4).

The high input impedance of the VCO simplifies the design of the low-pass filters by giving

the designer a wide choice of resistor/capacitor ranges. In order not to load the low-pass

filter, a demodulator output of the VCO input voltage is provided at pin DEM_OUT. In

contrast to conventional techniques, where the DEM_OUT voltage is one threshold

voltage lower than the VCO input voltage, the DEM_OUT voltage equals the VCO input. If

DEM_OUT is used, a series resistor (R

) should be connected from pin DEM_OUT to

GND; if unused, DEM_OUT should be left open. The VCO output (pin VCO_OUT) can be

connected directly to the comparator input (pin COMP_IN), or connected via a frequency

divider. When the VCO input DC level is held constant, the VCO output signal has a duty

cycle of 50 % (maximum expected deviation 1 %). A LOW-level at the inhibit input

(pin INH) enables the VCO and demodulator, while a HIGH-level turns both off to

minimize standby power consumption.

The only difference between the 74HC4046A and 74HCT4046A is the input level

specification of the INH input. This input disables the VCO section. The sections of the

comparator are identical, so that there is no difference in the SIG_IN or COMP_IN inputs

between the 74HC4046A and 74HCT4046A.

8.2 Phase comparators

The input signal can be coupled to the self-biasing amplifier at pin SIG_IN, when the

signal swing is between the standard HC family input logic levels. Capacitive coupling is

required for signals with smaller swings.
