Programmable PLL Clock Generator Single 16-Pin TSSOP

The CY22050 is programmable clock generator for use in networking, telecommunication, datacom, and other general-purpose applications. The CY22050 offers up to six configurable outputs in a 16-pin TSSOP, running off a 3.3 V power supply. The on-chip reference oscillator is designed to run off an 8–30-MHz crystal, or a 1–133-MHz external clock signal. The CY22050 has a single PLL driving 6 programmable output clocks. The output clocks are derived from the PLL or the reference frequency (REF). Output post dividers are available for either. Four of the outputs can be set as 3.3 V or 2.5 V, for use in a wide variety of portable and low-power applications.
