Triple PLL Field Programmable SS VersaClock Synthesizer

Description

The ICS345 field programmable clock synthesizer

generates up to nine high-quality, high-frequency clock

outputs including multiple reference clocks from a

low-frequency crystal or clock input. It is designed to

replace crystals and crystal oscillators in most

electronic systems.

Using ICS’ VersaClockTM software to configure PLLs

and outputs, the ICS345 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, and optional Spread Spectrum

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 ICS345 is also available in factory programmed

custom versions for high-volume applications.

Features

• Packaged as 20-pin SSOP (QSOP)

• Spread spectrum capability

• Eight addressable registers

• Replaces multiple crystals and oscillators

• Output frequencies up to 200 MHz at 3.3 V

• 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. For two output

clocks, see the ICS342. For three output clocks, see

the ICS343. For more than three outputs, see the

ICS345 or ICS348.

• Available in Pb (lead) free packaging
