LOCO™ PLL CLOCK MULTIPLIER

Description

The ICS501A LOCOTM is the most cost effective way to

generate a high quality, high frequency clock output

from a lower frequency crystal or clock input. The name

LOCO stands for Low Cost Oscillator, as it is designed

to replace 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 200

MHz.

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

different multiplication factors, allowing one chip to

output many common frequencies (see table on page

2).

The device also has an output enable pin which

tri-states the clock output when the OE pin is taken low.

This product is intended for clock generation. It has low

output jitter (variation in the output period), but input to

output skew and jitter are not defined or guaranteed.

For applications which require defined input to output

skew, use the ICS570B.
