USER CONFIGURABLE CLOCK

Description

The ICS525-01/02/11/12 are 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 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 standard

fundamental mode, inexpensive crystal to produce

output clocks up to 250 MHz. It 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

ICS307. For simple multipliers to produce common

frequencies, refer to the ICS50x family of parts, which

are smaller and more cost effective.

These products 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.
