CY22050
One-PLL General-Purpose
Flash-Programmable Clock Generator
One-PLL General-Purpose Flash-Programmable Clock Generator
Features Functional Description
Integrated phase-locked loop (PLL) The CY22050 is programmable clock generator for use in
networking, telecommunication, datacom, and other
Commercial and Industrial operation
general-purpose applications. The CY22050 offers up to six
configurable outputs in a 16-pin TSSOP, running off a 3.3 V
Flash-programmable
power supply. The on-chip reference oscillator is designed to run
Field-programmable
off an 830-MHz crystal, or a 1133-MHz external clock signal.
Low-skew, low-jitter, high-accuracy outputs The CY22050 has a single PLL driving 6 programmable output
clocks. The output clocks are derived from the PLL or the
3.3 V operation with 2.5 V output option
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
16-pin TSSOP package (CY22050)
in a wide variety of portable and low-power applications.
