HDMI output connector UM2048 HDMI output connector A standard HDMI output connector CN2 is implemented on DSI to HDMI adapter board. The output supports all video and graphics resolutions from 480i to 1080p at 30 Hz. Thanks to common-mode filter with ESD protection parts, HDMI output connector is complies with IEC 61000-4-2 level 4 standard.

UM2048 There are two sources of CEC signal on HDMI output connector on DSI to HDMI adapter board. One source (Default setting) is from ADV7533 and its clock is from X1 on the board. The other source is from CN1 and mother board. Some PCB reworks should be done when using the second source shown in Table 3.
