Functional Description
8-pin SOIC package (CY22381)
8-pin SOIC package with NiPdAu lead finish (CY223811)
CyClocks RT™ support
The CY22381 is the next-generation programmable Flash
programmable clock for use in networking, telecommunication,
datacom, and other general-purpose applications. The
CY22381 offers up to three configurable outputs in a 8-pin
SOIC, running off a 3.3V power supply. The on-chip reference
oscillator is designed to run off an 8–30-MHz crystal, or a
1–166-MHz external clock signal. The CY22381 has a three
PLLs driving 3 programmable output clocks. The output clocks
are derived from the PLL or the reference frequency (REF).
Output post dividers are available for either. The CY223811 is
the CY22381 with NiPdAu lead finish.
