PECL INPUT OSCAR USER CONFIGURABLE CLOCK

DATASHEET

ICS525-03

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 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.
