NOTICE - The following device(s) are recommended alternatives:

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