ICS8402AYI REV. A OCTOBER 16, 2007
General Description
The ICS8402I is a general purpose,
Crystal-to-LVCMOS/LVTTL High Frequency
Synthesizer and a member of the HiPerClockS
family of High Performance Clock Solutions from
IDT. The ICS8402I 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 ICS8402I make it an ideal clock source for
Gigabit Ethernet and SONET applications.
