9.1.3. TV-Out Reference Schematics
All signals along the left edge of the figure below are sourced directly from the COM Express Module. No additional pull-ups or terminations beyond
what is shown in the figure are required.
The 150 Ω termination to ground is important both for signal integrity and to establish the correct DC level on the line. All components shown in this
figure should be placed close to the Carrier Board connector shown in the figure.
