产品概述

TPF153 is low power consumption; single power supply (3.3V/5.5V), three channel video buffers, and it have 6dB gain with 220MHz 3dB bandwidth, which is suitable for Y'Pb'Pr', R'G'B', VGA/SVGA/XGA TPF153 is perfect to support HD video with very low power consumption; its high dynamic range can meet the most challenge HD system requirement.

As part of the TPF153 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 TPF153 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-Ω loads, allows for maximum flexibility as a video line driver. The 34.5-mA total quiescent current at 3.3 V makes it an excellent choice for power-sensitive video applications.TPF153 is available in SOIC-8 package.Its operation temperature range is from -40℃ to +85℃.
