- Typical Application
TPF131 is a specially designed for consumerapplications, high-performance, low-cost video reconstruction filter, itcombine excellent video performance and low power consumption perfectly. Itincorporates one high-definition (HD) filter channels. The filter featuresixth-order Butterworth characteristics that are useful as digital-to-analogconverter (DAC) reconstruction filters or as analog-to-digital converter (ADC)anti-aliasing filters. The HD filters can be bypassed to support HDCVI 1080i/720pvideo.
As part of the TP131 flexibility, the input can beconfigured for ac- or dc-coupled inputs. The 84-mV output level shift allowsfor a full sync dynamic range at the output with 0-V input. The ac-coupled modesinclude a transparent sync-tip clamp option for composite video (CVBS), Y', andG'B'R' signals. AC- coupled biasing for C'/P'B/P'R channels can easily beachieved by adding an external resistor to VS+.
The TP131 rail-to-rail output stage with 6-dB gain allowsfor both ac and dc line driving. The ability to drive two lines, or 75-Ω loads,allows for maximum flexibility as a video line driver. The 6-mA total quiescentcurrent at 3.3 V makes it an excellent choice for power-sensitive videoapplications.
TPF131 isavailable in SOT23-6 package (TPF131-TR). Its operationtemperature range is from −40°C to +85°C.
