PECL INPUT OSCAR™ USER CONFIGURABLE CLOCK

IDT® PECL INPUT OSCAR™ USER CONFIGURABLE CLOCK

Description

The ICS525-03 are the most flexible way to generate a

high-quality, high-accuracy, high-frequency clock

output from a PECL input. The name OSCaR stands

for OSCillator Replacement, as they are designed to

replace crystal oscillators in almost any electronic

system. The user can 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 (PLL) techniques, the device accepts a PECL

clock to produce output clocks up to 250 MHz, keeping

them frequency locked together. Resistors are for

PECL outputs only.

For simple multipliers to produce common frequencies,

refer to the LOCO

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.
