概述
TPF142 is a specially designed for consumer applications, high-performance, low-cost video reconstruction filter, it combine excellent video performance and low power consumption perfectly. It incorporates one standard-definition (CVBS) and one high-definition (HD) filter channels. 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 HD filters can be bypassed to support filters. The HD filters can be bypassed to support 1080p60 video or up to quad extended graphics array (QXGA) RGB video.
As part of the TP142 flexibility, the input can be configured for ac- or dc-coupled inputs. The 84-mV output level shift allows for 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 (CVBS), Y', and G'B'R' signals. ACcoupled biasing for C'/P'B/P'R channels can easily be achieved by adding an external resistor to VS+.
The TP142 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 maximum flexibility as a video line driver. The 14.5-mA total quiescent current at 3.3 V makes it an excellent choice for power-sensitive video applications.
TPF142 is available in MSOP-8 package (TPF142-VR) and TSSOP-14 package (TPF142-TR). Its operation temperature range is from −40° C to +85° C.
