Description

The MK3722 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. The patented on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to cause the output clocks to vary by ±115 ppm. Using ICS’ analog/digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 27 MHz pullable crystal input to produce a reference output and a selectable audio clock.
