ANALOG SIGNAL INTERCONNECT
For optimum performance, the analog outputs should each
have a source termination resistance to ground of 75 Ω (doubly
terminated 75 Ω configuration). This termination resistance
should be as close as possible to the ADV7125 to minimize
reflections.
Place the ADV7125 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
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.
