The 84320I-01 is a general purpose, dual output Crystal-to-3.3V Differential LVPECLHigh Frequency Synthesizer. The 84320I-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 84320I-01make it an ideal clock source for 10 Gigabit Ethernet, SONET, and Serial Attached SCSI applications.
