Features

Description

• Operating Frequency Range

The ’HC4046A and ’HCT4046A are high-speed silicon-gate

CMOS devices that are pin compatible with the CD4046B of

the “4000B” series. They are specified in compliance with

- Up to 18MHz (Typ) at V

= 5V

- Minimum Center Frequency of 12MHz at V

JEDEC standard number 7.

• Choice of Three Phase Comparators

- EXCLUSIVE-OR

The ’HC4046A and ’HCT4046A are phase-locked-loop

circuits that contain a linear voltage-controlled oscillator

(VCO) and three different phase comparators (PC1, PC2 and

PC3). A signal input and a comparator input are common to

each comparator.

- Edge-Triggered JK Flip-Flop

- Edge-Triggered RS Flip-Flop

• Excellent VCO Frequency Linearity

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 4046A forms a second-order loop

PLL. The excellent VCO linearity is achieved by the use of

linear op-amp techniques.

Standby Power Consumption
