With its exceptional video performance and very low power consumption, it is excellent choice for portable video applications. Integrated with a 6th-order Butterworth filter, TPF111 can be used as a DAC reconstruction filter or ADC anti-aliasing filter. With its -3d B frequency of 9MHz, it is an ideal choice for SD video applications including NTSC and PAL. TPF111 accepts both AC- and DC-coupled inputs and its flexible biasing options meet the requirement of the most demanding applications. The integrated Transparent Sync-tip Clamp circuit restores DC voltage level of an AC-coupled Video signal. It translates the sync tip of a CVBS, Y', or RGB signal to a fixed 40m V. External biasing resistors can be used to restore signals without sync tip such as Pb' or Pr'. Integrated level shifter then raises the clamped video signal by 80m V, assuring passing through of video signal without being distorted. When the signal is DC-coupled, the level shifter will raise the signal by 80m V. TPF111 may be used for different kinds of video buffering with 6d B gain(2V/V) and rail-to-rail...
