TSH173 Datasheet Single Supply Triple Video Buffer And Filter

Manufacturer: STMicroelectronics

Overview: TSH173 Triple video buffer with filter for SD video.

General Description

The TSH173 is a single supply triple video buffer featuring an internal gain of 6dB and an internal low pass filter of 8.2MHz cut-off frequency for each channel to fit with Standard Definition requirements for video line interfaces.

Another advantage of the TSH173 is its input DC level shifter to drive the video signal on a 75Ω video line without any damage to the synchronization tip, while using a single 5V power supply with no input capacitor.

The DC level shifter is internally fixed and optimized to keep the output video signal between low and high output rails in the best position to improve linearity.
