CMOS Phase Lock Loop

The 74VHC4046 is a low power phase lock loop utilizing advanced silicon-gate CMOS technology to obtain high fre- quency 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 input Logic levels. This device is similar to the CD4046 except that the Zener Diode of the metal Gate CMOS device has been replaced with a third phase Comparator By National Semiconductor Corporation
