ICS348

Stresses above the ratings listed below can cause permanent damage to the ICS348. 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 ICS348 field programmable clock synthesizer generates up to 9 high-quality, high-frequency clock outputs including multiple reference clocks from a low frequency crystal or clock input. The ICS348 has 4 independent on-chip PLLs and is designed to replace crystals and crystal oscillators in most electronic systems.

Using ICS' VersaClock^TM software to configure PLLs and outputs, the ICS348 contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include eight selectable configuration registers, up to two sets of four low-skew outputs.

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 ICS348 is also available in factory programmed custom versions for high-volume applications.
