84320-01 - Block Diagram
Description
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 frequency is programmed in steps equal to the value of the input reference 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 84320-01 make it an ideal clock source for 10 Gigabit Ethernet, SONET, and Serial Attached SCSI applications.
