Video ADC Gain
Unlike other products performing digital processing and using video DAC’s, this module does not scale the
composite video signal with digital multipliers. The overall gain is changed by adjusting analog parameters,
providing the user with as much dynamic range at –20% gain as at +20% gain. No analog input offset
adjustment is provided because the module calculates static offset corrections as the gain is changed.
Video Mode Selection
The video mode selection is used to set standard specific values (including gains and blanking values)
without having to provide video input. If the user has made a default standard selection of std. PAL and a
525 line signal arrives, the module will automatically change to US NTSC mode during the 525 line
signal’s presence. If a 525 line standard is selected as default and a 625 line signal is applied to the input,
the module will automatically change to std. PAL mode during the 625 line signal’s presence.
