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.
