DATASHEET
QUAD PLL FIELD PROGRAMMABLE VERSACLOCK SYNTHESIZER
ICS348
IDT / ICS QUAD PLL FIELD PROGRAMMABLE VERSACLOCK SYNTHESIZER 1
ICS348
REV L 051310
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. 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.
Features
Packaged as 20-pin SSOP (QSOP) (Pb-free)
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.
