The TPF147 is specially designed for consumer applications, high-performance, low-cost video reconstruction filter, it combines excellent video performance and low power consumption perfectly. It incorporates one selectable full high-definition (FHD) and one high-definition (HD) filter channel. All filters feature sixth-order Butterworth characteristics that are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters. The FHD filters can be bypassed to support 1080p60 video, and the HD filters can be bypassed to support 720p60 or 1080i60 video. As part of the TP147 flexibility, the input can be configured for ac- or dc-coupled inputs. The 84-mV output level shift allows a full sync dynamic range at the output with 0-V input. The ac-coupled modes include a transparent sync-tip clamp option for composite video (CVI), Y', and G'B'R' signals. ACcoupled biasing for C'/P'B/P'R channels can be easily achieved by adding an external resistor to VS+. The TP147 rail-to-rail output stage with 6-dB gain allows for both ac and dc line driving. The ability to drive two lines, or 75-Ω loads, allows for the maximum flexibility as a video line driver. The 6/11.5- mA total quiescent current at 3.3 V makes it an excellent choice for power-sensitive video applications. The TPF147 is available in a SOT23-6 package (TPF147-TR). Its operating temperature range is from −40°C to +85°C.
