Description
TPF141 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 TP141 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 TP141 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.
TPF141 is available in SOT23-6 package. Its operation
temperature range is from
−40°C
to +85°C.
