com 74VHC4046 CMOS Phase Lock Loop April 1994 Revised October 2003 74VHC4046 CMOS Phase Lock Loop General Description The VHC4046 is a low power phase lock loop utilizing advanced silicon-gate CMOS technology to obtain high frequency operation both in the phase comparator and VCO sections.
This device contains a low power linear voltage controlled oscillator (VCO), a source follower, and three phase comparators.
The three phase comparators have a common signal input and a common comparator input.
The signal input has a self biasing amplifier allowing signals to be either capacitively coupled to the phase comparators with a small signal or directly coupled with standard inp...
