Description
The 8432-11 is a general purpose, dual output Crystal-to-3.3V Differential LVPECL High Frequency Synthesizer. The 8432-11 has a selectable TEST_CLK or crystal inputs. The TEST_CLK input accepts LVCMOS or LVTTL levels and translates them to 3.3V LVPECL levels. The VCO operates at a frequency range of 200MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the input reference or crystal frequency. Output frequencies up to 700MHz for FOUT and 350MHz for FOUT/2 can be programmed using the serial or parallel interfaces to the configuration logic.
