QUAD PLL FIELD PROGRAMMABLE VERSACLOCK SYNTHESIZER
Description
The ICS348 field programmable clock synthesizer
generates up to 9 high-quality, high-frequency clock outputs
including multiple reference clocks from a low frequency
crystal or clock input. The ICS348 has 4 independent
on-chip PLLs and is designed to replace crystals and
crystal oscillators in most electronic systems.
Using IDT’s VersaClock
outputs, the ICS348 contains a One-Time Programmable
(OTP) ROM to allow field programmability. Programming
features include eight selectable configuration registers, 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 ICS348 is also available in factory programmed custom
versions for high-volume applications.
