Description

TRIPLE PLL FIELD PROGRAMM
The 345RPT is a field programmable clock synthesizer that 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 IDT VersaClock software to configure PLLs and outputs, the 345RPT 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 345RPT runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost.

The 345RPT is also available in factory programmed custom versions for high-volume applications.

Packaged as 20-pin SSOP (QSOP)
