SERIALLY PROGRAMMABLE CLOCK SOURCE DATASHEET ICS307-03 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.

SERIALLY PROGRAMMABLE CLOCK SOURCE

DATASHEET

ICS307-03

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.
