DATASHEET

LOCO™ PLL CLOCK MULTIPLIER

ICS501A

Description

Features

The ICS501A LOCO is the most cost effective way to

• Packaged as 8-pin SOIC (Pb-free) or die

• IDT’s lowest cost PLL clock

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.

• Zero ppm multiplication error

• Input crystal frequency of up to 27 MHz

• Input clock frequency of up to 50 MHz

• Output clock frequencies up to 200 MHz

• Extremely low jitter of 25 ps (one sigma)

• Compatible with all popular CPUs

• Duty cycle of 45/55 up to 200 MHz

• Nine selectable frequencies

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).

• Operating voltage of 3.3 V

The device also has an output enable pin which

• Tri-state output for board level testing

• 25 mA drive capability at TTL levels

• Ideal for oscillator replacement

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.

• Optimized for output frequencies of up to 200 MHz

(166 MHz maximum for industrial temperature

version)

• Industrial temperature version available

• Advanced, low power CMOS process
