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 layout
of the TSH344 dice has a very symmetrical geometry. this has a direct effect on the
synchronization of each channel, as shown in Figure 31. There is no delay detected
between channels when the same Vin signal is applied on the three inputs. Note that the
delay between the inputs and the outputs is equal to 4ns.
