Description
TPF111 is a low-cost reconstruction video filter optimized
for consumer video devices. With its video
performance and low power consumption, it is
the
choice
for portable video applications. Integrated with a 6
th
-
order Butterworth filter, TPF111 can be used as a DAC
reconstruction filter or ADC anti-aliasing filter. With its -3dB
frequency of 9MHz, it is a choice for SD video
applications including NTSC and PAL.
TPF111 accepts both AC- and DC-coupled inputs and its
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.
TPF111 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.
TPF111 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.
TPF111 operates from a single supply with wide voltage
range from +2.85V to +5.5V. Its low quiescent current of
3.85mA makes it a choice for battery-power or USB-
power applications.
TPF111 is available in SC70-5 package (TPF111-C) and
SOIC-8 package (TPF111-S). Its operation temperature
range is from −40°C to +85°C.
