OSCaRTM User Configurable PECL Clock
Description
The ICS525-04 OSCaRTM 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 OSCaRTM 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 LOCOTM 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.
