ICS84320-01
780MHZ, CRYSTAL-TO-3.3V DIFFERENTIAL
LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84320-01 is a general purpose, dual output Crystal-
to-3.3V Differential LVPECL High Frequency Synthesizer. The
ICS84320-01 has a selectable TEST_CLK or crystal
inputs. The VCO operates at a frequency range of 620MHz to
780MHz. The VCO frequencyis programmed in steps equal
to the value of the input reference or crystal frequency. The
VCO and output frequencycan be programmed using the
serial or parallel interfaces tothe configuration logic. The low
phase noise characteristicsof the ICS84320-01 make it an
ideal clock source for 10 Gigabit Ethernet, SONET, and
Serial Attached SCSI applications.
