ICS300/ICS301/ICS302

QTClock™ Quick Turn Clock Synthesizer

Description

Features

• Packaged as 8 pin SOIC

The ICS300 and ICS301 QTClocks™ generate a

high quality, high frequency clock output and a

reference from a low frequency crystal or clock

input. They are designed to replace crystals and

crystal oscillators in most electronic systems. The

ICS302 can accept a higher frequency clock input

to generate up to 200 MHz. The devices contain a

One Time Programmable (OTP) ROM which is

factory programmed with the PLL divider values

to output a broad range of frequencies, from 6 to

200 MHz, allowing customer requests for different

frequencies to be shipped in 1-3 days. Using

Phase-Locked-Loop (PLL) techniques, the devices

run from a standard fundamental mode,

• Quick turn frequency programming allows

samples in one to three days

• Replaces nearly any crystal or oscillator

• ICS300 produces up to 100 MHz at 3.3V,

ICS301 produces up to 200 MHz at 3.3V

ICS302 accepts up to 125 MHz clock input

• Easy to cascade with ICS5xx series

• Input crystal frequency of 5 - 27 MHz

• Input clock frequency of 2 - 125 MHz

• Low jitter - 50 ps one sigma

inexpensive crystal, or clock. They are smaller and

less expensive than one oscillator.

• Compatible with all popular CPUs

• Duty cycle of 45/55

• Operating voltages of 3.0 to 5.5V

• Full CMOS level outputs with 25mA drive

capability at TTL levels

• Tri-state output + PLL power down pin

• Advanced, low power CMOS process
