Description
TPF133A 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 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 TP133A 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 TP133A 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-loads, allows for maximum flexibility as a video line
driver. The 27.6-mA total quiescent current at 3.3 V makes it
an excellent choice for power-sensitive video applications.
TPF133A is available in SOIC-8 package. Its operation
temperature range is from 40°C to +85°C.
