CY22381 CY223811 Three-PLL General Purpose Flash Programmable Clock Generator Three-PLL General Purpose Flash Programmable Clock Generator Features Functional Description Three integrated phase-locked loops The CY22381 is the next-generation programmable Flash programmable clock for use in networking, telecommunication, Ultra-wide divide counters (eight-bit Q, eleven-bit P, and datacom, and other general-purpose applications. The CY22381 seven-bit post divide) 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 Improved linear crystal load capacitors designed to run off an 830-MHz crystal, or a 1166-MHz Flash programmability external clock signal. The CY22381 has a three PLLs driving 3 programmable output clocks. The output clocks are derived from Field programmability the PLL or the reference frequency (REF). Output post dividers Low-jitter, high-accuracy outputs are available for either. The CY223811 is the CY22381 with NiPdAu lead finish.
