This circuit is intended to provide automatic, precision amplitude control for video signals at the input to a video distribution amplifier board. It is meant to compensate for level impairments to the video signal so that the distributed outputs will be nominal.

  • .037 dB/LSB of granularity in amplitude adjustment.
  • Adjustment range : -6dB to +3.5dB (0.5 to 1.5)
  • Suitable for CVBS, S-Video, SD and ED Video formats.
  • Excellent delay and amplitude variation specifications.
