Typical Application

TPF140R is a specially designed for consumer applications,high-performance, low-cost video reconstruction filter, it combine excellentvideo performance and low power consumption perfectly. It incorporates one Fullhigh-definition (FHD) filter channels. The filter feature sixth-orderButterworth 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 filters. The FHDfilters can be bypassed to support 1080p60 video or up to quad extendedgraphics array (QXGA) RGB video.

As part of the TP140R flexibility, the input can be configured for ac- ordc-coupled inputs. The 84-mV output level shift allows for a full sync dynamicrange at the output with 0-V input. The ac-coupled modes include a transparentsync-tip clamp option for Y', and G'B'R' signals. AC- coupled biasing forC'/P'B/P'R channels can easily be achieved by adding an external resistor toVS+.

The TP140R rail-to-rail output stage with 6-dB gain allows for both ac anddc line driving. The ability to drive two lines, or 75-Ω loads, allows formaximum flexibility as a video line driver. The 11.5-mA total quiescent currentat 3.3 V makes it an excellent choice for power-sensitive video applications.

TPF140R is available in SOT23-6 package. Itsoperation temperature range is from −40°C to +85°C.
