Description

The 84321I is a general purpose, dual output Crystal-to- 3.3V Differential LVPECL High Frequency Synthesizer The 84321I 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 84321I make it an ideal clock source for Fibre Channel 1, Fibre Channel 2, 10 Gigabit Fibre Channel, Gigabit Ethernet and 10 Gigabit Ethernet applications.
