Overview

The 252MI-52LF is a low cost, dual-output, field programmable clock synthesizer. The 252MI-52LF can generate two output frequencies from 314 kHz to 200 MHz using up to two 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 252MI-52LF contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include 2 selectable configuration registers. The device employs Phase-Locked Loop (PLL) techniques to run 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 252MI-52LF is also available in factory programmed custom versions for high-volume applications.
