ESCRIPTION
The ICS84320I-01 is a general purpose, dual
output Crystal-to-3.3V Differential LVPECL
High Frequency Synthesizer and a member of
the HiPerClockS family of High Performance
Clock Solutions from ICS. The ICS84320I-01
has a selectable TEST_CLK or crystal inputs. 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 interfaces to the configuration logic. The
low phase noise characteristics of the ICS84320I-01
make it an ideal clock source for 10 Gigabit Ethernet,
SONET, and Serial Attached SCSI applications.
