CY22381

CY223811

Three-PLL General Purpose FLASH

Programmable Clock Generator

■ 8-pin SOIC package (CY22381)

Features

■ 8-pin SOIC package with NiPdAu lead finish (CY223811)

■ CyClocks RT™ support

■ Three integrated phase-locked loops

■ Ultra-wide divide counters (eight-bit Q, eleven-bit P, and

seven-bit post divide)

Functional Description

■ Improved linear crystal load capacitors

■ Flash programmability

■ The CY22381 is the next-generation programmable Flash

programmableclockforuseinnetworking, telecommunication,

datacom, and other general-purpose applications. The

CY22381 offers up to three configurable outputs in a 8-pin

SOIC, running off a 3.3V 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 CY22381 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 CY22381 with NiPdAu lead finish.

■ Field programmability

■ Low-jitter, high-accuracy outputs

■ Power-management options (Shutdown, OE, Suspend)

■ Configurable crystal drive strength

■ Frequency select option through external LVTTL Input

■ 3.3V operation
