8432-111 - Block Diagram
Description
The 8432-111 is a general purpose, dual output Differential-to-3.3V LVPECL High Frequency Synthesizer. The 8432-111 has a selectable differential CLK, nCLK pair or LVCMOS/LVTTL TEST_CLK. The TEST_CLK input accepts LVCMOS or LVTTL input levels and translates them to 3.3V LVPECL levels. The CLK, nCLK pair can accept most standard differential input 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 differential or single ended reference 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. The low phase noise characteristics and the multiple frequency outputs of the 8432-111 makes it an ideal clock source for Fibre Channel 1 and 2, and InfiniBand applications.
