... Electrical characteristics 3.1 Synchronization tip The TSH173, in single 0/5V supply, is designed to drive the video signal on the line without any damage to the synchronization tip. This is achieved by a small internal DC shift and a very low output rail. The DAC offset, as shown in Nevertheless, in order to minimize the DC component on the line, the output can be AC coupled by a capacitor Figure 18 ...

... For better quality bypassing, we recommend to add a 10nF capacitor, also placed as close as possible to the IC pins. Bypass capacitors must be incorporated for both the negative and the positive supply. Figure 21.
