ADV7123  
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.  
ANALOG SIGNAL INTERCONNECT  
Place the ADV7123 as close as possible to the output connec-  
tors, 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  
frequency power supply rejection.  
Additional information on PCB design is available in the  
AN-333 Application Note, Design and Layout of a Video  
Graphics System for Reduced EMI, which is available from  
Analog Devices at www.analog.com.
