General Description

The CY22180 is a low jitter clock generator for use in networking, telecommunication, datacom, consumer electronics, and other general purpose applications. The CY22180 offers a single programmable output and an optional copy of the input frequency. The on-chip reference oscillator is designed to run off a 10–30 MHz crystal, or a 10–133 MHz external clock signal. The output frequency range is 20–200 MHz. The CY22180 comes in an 8-pin SOIC, and requires a 3.3V power supply.
