DATASHEET FIELD PROGRAMMABLE TRIPLE OUTPUT SS VERSACLOCK SYNTHESIZER ICS343 Description The ICS343 is a low cost, triple-output, field programmable clock synthesizer. The ICS343 can generate three output frequencies from 250 kHz to 200 MHz, using up to three independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI). Using IDT’s VersaClock™ software to configure the PLL and output, the ICS343 contains a One-Time Programmable (OTP) ROM to allow field programmability. 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.
