PRELIMINARY INFORMATION

ICS503

LOCO™ PLL Clock Multiplier

Description

Features

• Packaged as 8 pin SOIC or die

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.

• ICS’ lowest cost PLL clock family

• Generates 16.9344 MHz for stereo codecs from

the 14.31818 MHz motherboard clock

• Can be cost effective in replacing a single

surface-mount crystal

• Can be driven by other 5xx series

• Input crystal frequency of 5 - 27 MHz

• Input clock frequency of 2 - 50 MHz

• Output clock frequencies up to 160 MHz

• Low jitter - 50 ps one sigma

Stored in the chip’s ROM is the ability to generate

9 different multiplication factors, allowing one

chip to be used in two or three different

applications (see page 2).

• Duty cycle of 45/55 up to 160 MHz

• Operating voltages of 3.0 to 5.5V

• Full CMOS level outputs with 25mA drive

capability at TTL levels

• Advanced, low power CMOS process
