CY22050 One-PLL General-Purpose Flash-Programmable Clock Generator One-PLL General-Purpose Flash-Programmable Clock Generator Features Functional Description Integrated phase-locked loop (PLL) The CY22050 is programmable clock generator for use in networking, telecommunication, datacom, and other Commercial and Industrial operation general-purpose applications. The CY22050 offers up to six configurable outputs in a 16-pin TSSOP, running off a 3.3 V Flash-programmable power supply. The on-chip reference oscillator is designed to run Field-programmable off an 830-MHz crystal, or a 1133-MHz external clock signal. Low-skew, low-jitter, high-accuracy outputs The CY22050 has a single PLL driving 6 programmable output clocks. The output clocks are derived from the PLL or the 3.3 V operation with 2.5 V output option reference frequency (REF). Output post dividers are available for either. Four of the outputs can be set as 3.3 V or 2.5 V, for use 16-pin TSSOP package (CY22050) in a wide variety of portable and low-power applications.
