DATASHEET

OSCAR™ USER CONFIGURABLE PECL CLOCK

Description

The ICS525-04 OSCaR

is the most flexible way to

generate a high quality, high frequency differential PECL

clock output from a crystal or CMOS clock input. The name

OSCaR

stands for Oscillator Replacement, as it is

designed to replace crystal oscillators in almost any

electronic system. Users can easily configure the device to

produce nearly any output frequency from any input

frequency by grounding or floating the select pins. Neither

microcontroller, software, nor device programmer are

needed to set the frequency. Using Phase Locked Loop

techniques, the device accepts a crystal or clock to produce

output clocks up to 156 MHz at 3.3V, keeping them

frequency locked together.

For simple multipliers to produce common frequencies,

refer to the LOCO

family of parts, which are smaller and

more cost effective.

This product is intended for clock generation. It has low

output jitter (variation in the output period), but input to

output skew and jitter are not defined nor guaranteed. For

applications which require defined input to output timing,

use the ICS527-02.
