Triple Video Buffer With Selectable Filter For HD And SD Video Applications

The TSH345 is a triple single-supply Video Buffer featuring an internal gain of 6 dB and selectable filtering for HD and SD Video outputs on 75 , Video lines. The TSH345 is ideal to drive either Y-C, CVBS, Y-U-V, Y-Pb-Pr or R-G-B s ig na l s f r om Video DAC outputs. The main advantage of this circuit is its input DC Level Shifter It allows you to drive Video signals on 75 Video lines without damage to the synchronization tip, and without either input or output capacitor while using a single 5 V power supply. The DC Level Shifter is internally fixed and optimized to keep the output Video signals between low and high output rails in the best position for the greatest linearity. By STMicroelectronics
