Delay between channels
Figure 30. Measurement of the delay between each channel
The delay between each video component is an important aspect in high definition video
systems. To properly drive the three video components without any relative delay, the
TSH343 dice layout has a very symmetrical geometry. The effect is direct on the
synchronization of each channel, as shown in
channels when the same V
between the inputs and the outputs is 4ns.
