Product Overview

The CD74HC4046AM is a CMOS logic high-speed Phase-locked-loop with VCO. This device contains 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.
  • Choice of 3-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
  • Green product and no Sb/Br

Applications

Clock & Timing, Motor Drive & Control, Industrial
