Functional Description
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.
The CY220501 is the CY22050 with NiPdAu lead finish.
