Description

TPF140 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 Full high-definition

(FHD) filter channels. The filter 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 filters. The FHD filters can be bypassed

to support 1080p60 video or up to quad extended graphics

array (QXGA) RGB video.

As part of the TP140 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 Y', and G'B'R' signals. AC- coupled biasing

for C'/P'B/P'R channels can easily be achieved by adding an

external resistor to VS+.

The TP140 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 11.5-mA total quiescent current at 3.3 V makes it

an excellent choice for power-sensitive video applications.

TPF140 is available in SOT23-6 package. Its operation

temperature range is from

−40°C

to +85°C.
