74HC7046A Phase-locked-loop

The 74HC/HCT7046 are high-speed Si-gate CMOS devices and are specified in compliance with JEDEC standard no. 7. The 74HC/HCT7046 are phase-locked-loop circuits that comprise a linear voltage-controlled oscillator (VCO) and two different phase comparators (PC1 and PC2) with a common signal input amplifier and a common comparator input. A lock detector is prov.
