ICS525-04

OSCaR User Configurable PECL Clock

Description

Features

The ICS525-04 OSCaR is the most flexible way to

generate a high quality, high frequency differential

PECL clock output from a crystal or CMOS clock input.

• Packaged as 28 pin SSOP (150 mil body)

• Highly accurate frequency generation

• User determines the output frequency by setting all

The name OSCaR stands for Oscillator

internal dividers

Replacement, as it is designed to replace crystal

oscillators in almost any electronic system. Users can

easily configure the device to produce nearly any

output frequency from any input frequency by

grounding or floating the select pins. Neither

microcontroller, software, nor device programmer are

needed to set the frequency. Using Phase Locked Loop

techniques, the device accepts a crystal or clock to

produce output clocks up to 156 MHz at 3.3V, keeping

them frequency locked together.

• Eliminates need for custom oscillators

• No software needed

• Pull-ups on select inputs

• Input crystal frequency of 5 - 27 MHz

• Input clock frequency of 2 - 50 MHz

• Output clock frequencies up to 156 MHz at 3.3V

• Output clock frequencies up to 200 MHz at 5V

• Very low jitter

• PECL levels set by external resistors

• Operating voltage of 3.3V or 5V

• Ideal for oscillator replacement

• Industrial temperature version available

• Advanced, low power CMOS process

For simple multipliers to produce common frequencies,

refer to the LOCO family of parts, which are smaller

and more cost effective.

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 nor guaranteed.

For applications which require defined input to output

timing, use the ICS527-02.
