IDT, Integrated Device Technology Inc ICS341MP

Description
The ICS341 is a low-cost, single-output, field-programmable clock synthesizer. It generates output frequencies from 250 kHz to 200 MHz and can employ Spread Spectrum techniques to reduce system electromagnetic interference (EMI).
Using IDT's VersaClock software, the ICS341 can be configured with four selectable configuration registers. It employs Phase-Locked Loop (PLL) techniques to run from a standard fundamental mode, inexpensive crystal, or clock. This allows it to 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.
