Digital Signal Interconnect
The digital signal lines to the ADV7127 should be isolated as
much as possible from the analog outputs and other analog
circuitry. Digital signal lines should not overlay the analog
power plane.
Due to the high clock rates used, long clock lines to the ADV7127
should be avoided so as to minimize noise pickup.
Any active pull-up termination resistors for the digital inputs
should be connected to the regular PCB power plane (V
not the analog power plane.
Analog Signal Interconnect
The ADV7127 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.
For optimum performance, the analog outputs should each
have a source termination resistance to ground of 75

mize reflections.
