ICS281

The ICS281 field programmable spread spectrum clock synthesizer generates up to three high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals, crystal oscillators and stand alone spread spectrum devices in most electronic systems.

Using ICS' VersaClockTM software to configure PLLs and outputs, the ICS281 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include input/output frequencies, spread spectrum amount and eight selectable configuration registers.

Using Phase-Locked Loop (PLL) techniques, the ICS281 runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost.

The ICS281 is also available in factory programmed custom versions for high-volume applications.
