The CY22381SXI-186 is the next-generation programmable Flash programmable clock for use in networking, telecommunication, datacom, and other general-purpose applications. The CY22381SXI-186 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 CY22381SXI-186 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 CY22381SXI-186 with NiPdAu lead finish.
