機能説明

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 3.3 V 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.
