ICS357
PECL/LVDS Spread Spectrum QTClock
PRELIMINARY INFORMATION
Packaged as 16 pin TSSOP and SOIC
Quick turn frequency programming allows
samples as quickly as one day
Ideal for the High Speed Serial ATA applications
Spread spectrum outputs
Output frequencies up to 200 MHz at 3.3V
Input crystal frequency of 5 - 27 MHz
Input clock frequency of 2 - 50 MHz
Duty cycle of 45/55
Operating voltage of 3.3 V or 5 V
Advanced, low power CMOS process
The ICS357 quick turn (QTClock) generates a high
quality, high frequency, spread spectrum differential
PECL/LVDS clock from a clock or crystal input. The
ICS357 contains a One-Time Programmable (OTP)
ROM which is factory programmed with PLL divider
values to output a broad range of frequencies up to
200 MHz. This allows customer requests for different
input and output frequencies to be shipped in one to
three days.
Using Phase-Locked-Loop (PLL) techniques, the
device runs from a standard fundamental mode,
inexpensive crystal, or clock. It can replace multiple
devices, saving board space and cost.
