DATASHEET
QUAD PLL FIELD PROGRAMMABLE VERSACLOCK SYNTHESIZER
ICS348
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 VersaClockTM software to configure PLLs and 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.
