PRELIMINARY INFORMATION

ICS348-22

Quad PLL Field Programmable VersaClock Synthesizer

Description

Features

The ICS348-22 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 ICS348-22 has

four independent on-chip PLLs and is designed to

replace crystals and crystal oscillators in most

electronic systems.

• Packaged as 20-pin SSOP (QSOP)

• Eight addressable registers

• Replaces multiple crystals and oscillators

• Output frequencies up to 189 MHz at 3.3 V

• Input crystal frequency of 25 MHz

• Up to nine reference outputs

Using ICS’ VersaClock software to configure PLLs

• Up to two sets of four low-skew outputs

• Operating voltages of 3.3 V

and outputs, the ICS348-22 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.

• Advanced, low power CMOS process

• Available in Pb (lead) free packaging

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.
