ICS252

Stresses above the ratings listed below can cause permanent damage to the ICS252. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

The ICS252 is a low cost, dual-output, field
programmable clock synthesizer. The ICS252 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 ICS' VersaClock™ software to configure the PLL
and output, the ICS252 contains a One-Timem Programmable (OTP) ROM to allow field programmability. Programming features include 4 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 ICS252 is also available in factory programmed custom versions for high-volume applications.
