Any active pull-up termination resistors for the digital inputs
should be connected to the regular PCB power plane (V
CC
) and
not the analog power plane.
Analog Signal Interconnect
The ADV7123 should be located as close as possible to the
output connectors thus minimizing noise pickup and reflections
due to impedance mismatch.
The video output signals should overlay the ground plane and
not the analog power plane, thereby maximizing the high fre-
quency power supply rejection.

Figure 25. Typical Connection Diagram
For optimum performance, the analog outputs should each have
a source termination resistance to ground of 75
(doubly
terminated 75
configuration). This termination resistance
should be as close as possible to the ADV7123 to minimize
reflections.
Additional information on PCB design is available in an applica-
tion note entitled “Design and Layout of a Video Graphics
System for Reduced EMI.” This application note is available
from Analog Devices, publication no. E1309–15–10/89.
