With its video performance and low power consumption, it is choice for portable video applications. Integrated with 3 6th-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 ACand 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 USBpower applications. TPF113 is available in SOIC-8 package. Its operation temperature range is from −40°C to +85°C. 3-SDTV Filter 6th-order Butterworth Low-Pass Filter： 9MHz -3dB Bandwidth, 57.2dB Attenuation(27MHz) Support Multiple Input Biasing: Applications      Video Signal Amplification Set-Top Box Video Driver PVR、DVD Player Video Buffer Video Buffer for Portable or USB-Powered Video Devices HDTV Related Resources AN-1201: Application notes of TPF1xx Function Block TPF113 +Vs gm C hannel 1 In p u t 80m V Level S h ift LP F S y n c -T ip C la m p (D C R e s to re ) +Vs gm C hannel 2 In p u t +Vs REV 2.3 www.3peakic.com gm 6dB Channel 2 O u tp u t 6dB Channel 3 O u tp u t 80m V Level S h ift S y n c -T ip C la m p (D C R e s to re ) C hannel 3 In p u t Channel 1 O u tp u t 6 -P o le 9M H z LP F +Vs 6dB 6 -P o le 9M H z 80m V Level S h ift LP F S y n c -T ip C la m p (D C R e s to re ) 6 -P o le 9M H z GND ©2011 3Peak Incorporated.
