IDT 8343AYI-01LF

Overview

The 8343AY-01LF is a low cost, triple-output, field programmable clock synthesizer. The 8343AY-01LF 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 8343AY-01LF 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 device 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 8343AY-01LF is also available in factory-programmed custom versions for high-volume applications.
