ICS503

The ICS503 is a member of the LOCO™ family,the most cost effective way to generate a high quality, high frequency clock output from a low frequency crystal or clock input. The name LOCO stands for LOw Cost Oscillator, as it is designed to replace crystals and crystal oscillators in most electronic systems. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 160 MHz.

Stored in the chip's ROM of the ICS503 is the ability to generate 9 different multiplication factors, allowing one chip to be used in two or three different applications (see page 2).
