ICS84320I-01
780MHZ, CRYSTAL-TO-3.3V DIFFERENTIAL
LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84320I-01 is a general purpose, dual output
Crystal-to-3.3V Differential LVPECLHigh Frequency
Synthesizer. The ICS84320I-01 has a selectable
TEST_CLK or crystal inputs. The VCOoperates at a
frequency range of 620MHz to 780MHz. The VCO frequency
is programmed in steps equal to thevalue of the input
reference or crystal frequency. The VCO and output
frequency can be programmed using theserial or parallel
interfaces to the configuration logic. The low phase noise
characteristics of the ICS84320I-01make it an ideal clock
source for 10 Gigabit Ethernet, SONET, and Serial Attached
SCSI applications.
