HiPerClockS鈩?/div>
quency Synthesizer and a member of the
HiPerClockS鈩?family of High Performance Clock
Solutions from ICS. The ICS84320-01 has a se-
lectable 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 refer-
ence 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 ICS84320-01 make it an ideal clock source for 10 Gigabit
Ethernet, SONET, and Serial Attached SCSI applications.
