LOCO™ PLL CLOCK MULTIPLIER

Description

The ICS501B LOCOTM is the most cost effective way to

generate a high-quality 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 20

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.

Features

• Packaged as 8 pin SOIC or die

• Available in Pb (lead) free package

• Duty cycle of 45/55 up to 20 MHz

• Nine selectable frequencies

• Operating voltage of 3.3 V or 5.5 V

• Tri-state output for board level testing

• 25 mA drive capability at TTL levels

• Ideal for oscillator replacement

• Industrial temperature version available

• Advanced, low-power CMOS process
