Description

The CY22381SXC-19 is a next-generation programmable Flash programmable clock designed for use in networking, telecommunication, datacom, and other general-purpose applications. It offers up to three configurable outputs in an 8-pin SOIC package, and operates on a 3.3V power supply. The on-chip reference oscillator can be driven by either an 8-30MHz crystal or a 1-166MHz external clock signal. With three PLLs, the CY22381SXC-19 can generate three programmable output clocks derived from the PLL or the reference frequency (REF). It also features output post dividers and a low-jitter, high-accuracy output. In addition, it offers various power-management options, configurable crystal drive strength, and support for frequency select option through an external LVTTL Input. The CY22381SXC-19 is available in an 8-pin small outline integrated circuit (SOIC) package.
