.. 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 parator and VCO sections. This device contains a low power linear voltage controlled oscillator (VCO), a source follower, and three phase parators. The three phase parators have a mon signal input and a mon parator input. The signal input has a self biasing amplifier allowing signals to be either capacitively coupled to the phase parators with a small signal or directly coupled with standard...
