DescriptionFIELD PROGRAMMABLE TRIPLE
The 343MPLFT is a low-cost, triple-output, field programmable clock synthesizer. The 343MPLFT can generate an output frequency from 250 kHz to 200 MHz, using up to three independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electromagnetic interference (EMI).
Using IDT VersaClock software to configure the PLL and output, the 343MPLFT 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.
The 343MPLFT also has a power-down feature that tri-states the clock outputs and turns off the PLLs when the PDTS pin is taken low.
The 343MPLFT is also available in factory programmed custom versions for high-volume applications.
