Product Overview

The CD74HC4046AE is a high speed silicon-gate CMOS logic Phase-Locked-Loop with VCO and compatible with the CD4046B of the "4000B" series. They are specified in compliance with JEDEC standard number 7. The HC4046A 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. 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.
  • Operating frequency range-up to 18MHz (typical) at VCC=5V
  • Choice of three phase comparators
  • Excellent VCO frequency linearity
  • VCO-inhibit control for on/off keying and for low standby power consumption
  • Minimal frequency drift
  • Balanced propagation delay and transition times
  • Significant power reduction compared to LSTTL Logic ICs
