TRIPLE PLL FIELD PROG. SPREAD SPECTRUM CLOCK SYNTHESIZER ICS290
Description
The ICS290 field programmable spread spectrum clock
synthesizer generates up to eight 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 VersaClock
outputs, the ICS290 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 four low-skew outputs.
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 ICS290 is also available in factory programmed custom
versions for high-volume applications.
