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
