BDM-610000049 Rev G Chapter 3: Connecting the cpuModule 33
LVDS Flat Panel Video Connector (CN19)
Table 13 provides the pinout of the Flat Panel Video connector (CN19). FP_VCC is configured for +3.3V by
default. Contact RTD to have FP_VCC configured for +5 V. FP_VBKLT can be either +5 V or +12 V, and can be
selected with JP9. See Jumper Settings and Locations on page 86 for more details.
Table 14 lists several LVDS panels that were tested with this cpuModule. When evaluating a panel to be used with
this cpuModule, review the specifications of the tested panels to assure compatability.
