Precision Amplitude Control for Analog Video PRECISIONAMPLITUDECONTROL-REF (ACTIVE)
See the Important Notice and Disclaimer covering reference designs and other TI resources.
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.
