Description
TPF113 is a 3-channel reconstruction video filter optimized
for consumer video devices. With its video
performance and low power consumption, it is choice for
portable video applications. Integrated with 3 6
th
-order
Butterworth filter, TPF113 can be used as a DAC
reconstruction filter or ADC anti-aliasing filter. With its -3dB
frequency of 9MHz, it is an choice for SD video
applications including NTSC and PAL.
TPF113 accepts both AC- and DC-coupled inputs and its
flexible biasing options meet the requirement of the most
demanding applications. The integrated Transparent Sync-tip
Clamp circuit restores DC voltage level of an AC-coupled
Video signal. It translates the sync tip of a CVBS, Y', or RGB
signal to a fixed 40mV. External biasing resistors can be
used to restore signals without sync tip such as Pb' or Pr'.
Integrated level shifter then raises the clamped video signal
by 80mV, assuring passing through of video signal without
being distorted. When the signal is DC-coupled, the level
shifter will raise the signal by 80mV.
TPF113 may be used for different kinds of video buffering
with 6dB gain(2V/V) and rail-to-rail output. It supports AC-
and DC-coupling at the output.
TPF113 is designed to have exceptional ESD rating. It is a
choice of protecting the main video processor chip from ESD
or surge strikes in applications such as set-top-boxes.
TPF113 operates from a single supply with wide voltage
range from +3.0V to +5.5V. Its very quiescent current of
3.85mA makes it an choice for battery-power or USB-
power applications.
TPF113 is available in SOIC-8 package. Its operation
temperature range is from
−40°C
to +85°C.
