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.
