概述
TPF111 is a low-cost reconstruction video filter optimized for consumer video devices. With its exceptional video performance and very low power consumption, it is excellent choice for portable video applications. Integrated with a 6th-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 an ideal choice for SD video applications including NTSC and PAL.
TPF111 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.
TPF111 may be used for different kinds of video buffering with 6dB gain(2V/V) and rail-to-rail output. It supports ACand DC-coupling at the output.
TPF111 is designed to have exceptional ESD rating. It is a great 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 very low quiescent current of 3.85mA makes it an perfect 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.
