The MM74HC4046 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 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. Phase Comparator I is an exclusive OR (XOR) gate. It provides a digital error signal that maintains a 90 phase shift between the VCO's center frequency and the input signal (50% duty cycle input waveforms) Product Highlights: Low dynamic power consumption: (VCC = 4.5V) Maximum VCO operating frequency: 12 MHz (VCC = 4.5V) Fast comparator response time (VCC = 4.5V) Comparator I: 25 ns Comparator II: 30 ns Comparator III: 25 ns VCO has high linearity and high temperature stability
