NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings are stress specifications only. Functional operation of product at these conditions or any conditions beyond those listed in the DC Characteristics or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

The ICS843101I-312 is a low phase-noise frequency margining synthesizer with frequency margining capability and is a member of the HiPerClockS™ family of high performance clock solutions from ICS. In the default mode, the device nominally generates a 312.5MHz LVPECL output clock signal from a 25MHz crystal input. There is also a frequency margining mode available where the device can be programmed, using the serial interface, to vary the output frequency up or down from nominal in 2% steps. The ICS843101I-312 is provided in a 16-pin TSSOP.
