36 CMA24BT cpuModule
BDM-610000087 Rev A
DisplayPort Connector (CN19)
The DisplayPort connector on the CMA24BT cpuModule is a standard PC DisplayPort connector complete
with latch holes to provide a rugged connecting solution for latching DisplayPort cables.
The DisplayPort supports all mandatory features of the VESA Embedded DisplayPort (eDP) 1.3 standard
and supports audio over the connection. Full bandwidth transmission is supported over a two meter cable,
with reduced bandwidth transmission supported up to a length of 15 meters.
The connection can directly output single-link HDMI and DVI signals by using a simple passive adapter.
Passive adapters acheive HDMI and DVI signaling by adjusting the lower signal levels output by the
connector.
Table 10 provides the pinout of the DisplayPort connector.
