Overview

The CY22381FXCT is the next-generation programmable Flash programmable clock for use in networking, telecommunication, datacom, and other general-purpose applications. The CY22381FXCT 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 CY22381FXCT 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 CY22381FXCT with NiPdAu lead finish.

■ Three integrated phase-locked loops ■ Ultra-wide divide counters (eight-bit Q, eleven-bit P, and seven-bit post divide) ■ Improved linear crystal load capacitors ■ Flash programmability ■ Field programmability ■ Low-jitter, high-accuracy outputs ■ Power-management options (Shutdown, OE, Suspend) ■ Configurable crystal drive strength ■ Frequency select option through external LVTTL Input ■ 3.3 V operation ■ 8-pin small outline integrated circuit (SOIC) package (CY22381) ■ 8-pin SOIC package with NiPdAu lead finish (CY223811) ■ CyClocks RT™ support
