Features

Description

• Center Frequency of 18MHz (Typ) at V

Minimum Center Frequency of 12MHz at V

= 5V,

The CD74HC7046A and CD74HCT7046A high-speed

silicon-gate CMOS devices, speciﬁed in compliance with

JEDEC Standard No. 7A, are phase-locked-loop (PLL)

circuits that contain a linear voltage-controlled oscillator

(VCO), two-phase comparators (PC1, PC2), and a lock

detector. A signal input and a comparator input are common

to each comparator. The lock detector gives a HIGH level at

pin 1 (LD) when the PLL is locked. The lock detector

CC = 4.5V

capacitor must be connected between pin 15 (C ) and pin

8 (Gnd). For a frequency range of 100kHz to 10MHz, the

lock detector capacitor should be 1000pF to 10pF,

respectively.

• Minimal Frequency Drift

• Zero Voltage Offset Due to Op-Amp Buffer

ject

The signal input can be directly coupled to large voltage

signals, or indirectly coupled (with a series capacitor) to

small voltage signals. A self-bias input circuit keeps small

voltage signals within the linear region of the input ampliﬁers.

With a passive low-pass ﬁlter, the 7046A forms a second-

order loop PLL. The excellent VCO linearity is achieved by

the use of linear op-amp techniques.
