ICS8402
350MHZ, CRYSTAL-TO-LVCMOS / LVTTL
FREQUENCY SYNTHESIZER
GENERAL 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 VCO operates at a frequency range of 250MHz
to 700MHz. 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 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.
