ICS291 - TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER

Datasheet Summary

Description

The ICS291 field programmable spread spectrum clock synthesizer generates up to six high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input.

Features

  • include input/output frequencies, spread spectrum amount, eight selectable configuration registers and up to two sets of three low-skew outputs. Each of the two output groups are powered by a separate VDDO voltage. VDDO may vary from 1.8 V to VDD. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The ICS291 is also available in factory programmed.

www.DataSheet4U.com DATASHEET TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS291 Description The ICS291 field programmable spread spectrum clock synthesizer generates up to six high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals, crystal oscillators and stand alone spread spectrum devices in most electronic systems. Using IDT’s VersaClockTM software to configure PLLs and outputs, the ICS291 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include input/output frequencies, spread spectrum amount, eight selectable configuration registers and up to two sets of three low-skew outputs.
