Triple PLL Field Programmable Spread Spectrum VersaClock Synthesizer

The ICS345 is a VersaClock supported, 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 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. 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 frequencies from 2 to 50 MHz Up to nine reference outputs Up to two sets of four low-skew outputs Operating voltage 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 package click here for VersaClock Software page By Integrated Device Technology
