DATASHEET

SERIALLY PROGRAMMABLE CLOCK SOURCE

Description

The ICS307-03 is a dynamic, serially programmable clock

source which is flexible and takes up minimal board space.

Output frequencies are programmed via a 3-wire SPI port.

An advanced PLL coupled to an array of configurable

output dividers and three outputs allows low-jitter

generation of frequencies from 200 Hz to 270 MHz.

The device can be reprogrammed during operation, making

it ideal for applications where many different frequencies

are required, or where the output frequency must be

determined at run time. Glitch-free frequency transitions,

where the clock period changes slightly over many cycles,

are possible.
