IDT / ICS TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER 1
ICS291
REV F 051310
Description
The ICS291 field programmable spread spectrum clock
synthesizer generates up to six high-quality, high-frequency
clock outputs including multiple reference clocks from a
low-frequency crystal input. It is designed to replace
crystals, crystal oscillators and stand alone spread
spectrum devices in most electronic systems.
Using IDT’s VersaClockTM software to configure PLLs and
outputs, the ICS291 contains a One-Time Programmable
(OTP) ROM for field programmability. Programming
features include input/output frequencies, spread spectrum
amount, eight selectable configuration registers and up to
two sets of three low-skew outputs.
Each of the two output groups are powered by a separate
VDDO voltage. VDDO may vary from 1.8 V to VDD.
Using Phase-Locked Loop (PLL) techniques, the device
runs from a standard fundamental mode, inexpensive
crystal, or clock. It can replace multiple crystals and
oscillators, saving board space and cost.
The ICS291 is also available in factory programmed custom
versions for high-volume applications.
