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
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
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,
inexpensive crystal, or clock. They are smaller and
less expensive than one oscillator.
