DESCRIPTION

· The TSH173 is a single supply triple video buffer with a 6dB internal gain and an 8.2MHz low pass filter per channel, designed for Standard Definition video line interfaces.

· It includes an internal DC level shifter to safely drive video signals on a 75Ω line without damaging the synchronization tip, operating on a single 5V power supply without needing an input capacitor.

· Optimized to maintain video signal linearity between output rails, it is suitable for R-G-B, Y-Pb-Pr, or Y-C-C VBS driving from video DAC outputs, available in an SO8 plastic package.

FEATURES

· Operates on a 4.5V to 5.5V single supply.

· Capable of driving R-G-B, Y-Pb-Pr, Y-C-C VBS signals.

· Features three channels with 6dB gain buffers and 8.2MHz video reconstruction filters for SD.

· Includes three internal input DC level shifters; no input capacitor required.

· Exhibits very low harmonic distortion.

· Each output can drive AC- or DC-coupled 150Ω loads.

· Tested on a 5V power supply with data min. and max. verified during production.

APPLICATIONS

· Set top boxes.

· DVD players/recorders.

· High-end video systems.

· Standard definition TV (SD).

· Multimedia products.
