STMicroelectronics TSH173 Triple Video Buffer Datasheet
The TSH173 is a single-supply triple video buffer designed for standard definition (SD) video line interfaces. It features an internal gain of 6dB and a fifth-order low-pass filter with an 8.2MHz cut-off frequency per channel to reconstruct the video signal. A key advantage is its built-in DC level shifter, which allows driving a 75Ω video line from a single 4.5V to 5.5V supply without requiring input capacitors or damaging the synchronization tip.
