3.3 FPD-Link Video Data Output

The FPD-Link video data output accepts a 20-pin IDC cable or similar 0.1 inch spaced connector. Connect the clock and 4 FPD-Link (LVDS) data pairs here. Video data mapping is determined from the MAPSEL switch, located on the mode select switch block (S2).

The required standard 100Ω differential termination is not populated onboard by default, but can be populated at R13, R14, R16, R17, and R19, located under the output connector (J5). Many sink devices (such as displays) have termination closer to the connector, or integrated into the module or board. Check the specific target device or module to verify that proper LVDS termination is used.
