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 ICS84021 is a general purpose, Crystal-to- LVCMOS/LVTTL High Frequency Synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS84021 has a selectable TEST_CLK or crystal input. The VCO operates at a frequency range of 620MHz to 780MHz. The VCO frequency is programmed in steps equal to the value of the input reference or crystal frequency. The VCO and output frequency can be programmed using the serial or parallel interface to the configuration logic. The low phase noise characteristics of the ICS84021 make it an ideal clock source for Gigabit Ethernet, SONET, Fibre Channel 1 and 2, and Infiniband applications.
