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

seven-bit post divide)

datacom, and other general-purpose applications. The CY22381

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 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.

■ 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
