Description
TPF134A 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 three 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 TP134A 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. AC- coupled biasing for C'/P'B/P'R channels can
easily be achieved by adding an external resistor to VS+.
The TP134A 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 31.5-mA total quiescent current at 3.3 V makes it
an excellent choice for power-sensitive video applications.
TPF134A is available in MSOP-10 package (TPF134A-V)
and TSSOP-14 package (TPF134A-T). Its operation
temperature range is from −40°C to +85°C.
