Advance Product Information

VSC6511

The output swing of the VSC6511 is controlled through the ISETx pins and a VREF input. By connecting

an 1.78K ohm resistor, 1%, between VSS and ISETx the output swing will be controlled to within 800mV +/-

7%. An optional bandpass voltage reference may be used to further tighten the output swings by accurately driv-

ing the VREF input.

Configuration Modes:

The MODE(1:0) inputs configure the VSC6511 into its different modes of operation. The table below sum-

marizes the different signals and circuits in the VSC6511 that change function in the different modes.
