Description

USER CONFIGURABLE CLOCK
The 525R-02ILF is the most flexible way to generate a high-quality, high-accuracy, high-frequency clock output from an inexpensive crystal or clock input. The user can easily configure the device to produce nearly any output frequency from any input frequency by grounding or floating the select pins. Neither microcontroller nor software nor device programmer are needed to set the frequency. Using Phase-Locked-Loop (PLL) techniques, the 525R-02ILF accepts a standard fundamental mode, inexpensive crystal to produce output clocks up to 250 MHz. 525R-02ILF can also produce a highly accurate output clock from a given input clock, keeping them frequency locked together. For similar capability with a serial interface, use the ICS 307.

These 525R-02ILF are intended for clock generation. They have 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 ICS527-01.
