The CY22381 is a next-generation programmable Flash programmable clock for networking, telecommunications, data communications, and other general purpose applications. The CY22381 offers up to three configurable outputs in an 8-pin SOIC, powered by a 3.3V power supply.
Pinouts
The on-chip reference oscillator is designed to run crystals at 8-30 mhz, or external clock signals at 1-166 mhz. The CY22381 has three PLLS driving three programmable output clocks. The output clock is derived from the PLL or reference frequency (REF). The post-output splitter can be used for either.
