Description

The ICS8402 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 ICS8402 has a selectable TEST_CLK or crystal inputs. The V^_CO operates at a frequency range of 250MHz to 700MHz. The V^_CO frequency is programmed in steps equal to the value of the input reference or crystal frequency. The V^_CO and output frequency can be programmed using the serial or parallel interfaces to the configuration logic. The low phase noise characteristics of the ICS8402 make it an ideal clock source for Gigabit Ethernet and SONET applications.
