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 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. 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.

ICS348

Features

•

Packaged as 20-pin SSOP (QSOP)

Eight addressable registers

Replaces multiple crystals and oscillators

Output frequencies up to 200 MHz at 3.3V

Input crystal frequency of 5 to 27 MHz

Input clock frequency of 2 to 50 MHz

Up to nine reference outputs

Up to two sets of four low-skew outputs

Operating voltages of 3.3 V

Advanced, low power CMOS process

For one output clock, use the ICS341 (8-pin). For two

output clocks, use the ICS342 (8-pin). For three output

clocks, use the ICS343 (8-pin). For more than three

outputs, use the ICS345 or ICS348.

•

Available in Pb (lead) free packaging
