ADV7320/ADV7321
Analog Signal Interconnect
Locate the ADV7320/ADV7321 as close as possible to the output
connectors to minimize noise pickup and reflections due to
impedance mismatch.
For optimum performance, each analog output should be
source- and load-terminated, as shown in Figure 91. The
termination resistors should be as close as possible to the
ADV7320/ADV7321 to minimize reflections.
For optimum performance, it is recommended that all decoupling
and external components relating to the ADV7320/ADV7321 are
located on the same side of the PCB and as close as possible to
the ADV7320/ADV7321. Unused inputs should be tied to ground.
ALL COMPONENTS IN DASHED BOXES MUST BE LOCATED ON THE SAME SIDE
OF THE PCB AS THE ADV7320/ADV7321 AND AS CLOSE AS POSSIBLE TO THE ADV7320/ADV7321.
