DSI to HDMI 

The Qualcomm APQ8053 Processor does not include a built-in HDMI interface. The ERAGON624 has 
the built-in MIPI-DSI 4 lanes interface, which is used, as a source for the HDMI output. A DSI to HDMI 
Bridge Board can be used to performs this task and it supports a resolution from 480p to 720p at 30Hz. 

 

While  the  ADV7533  on  the  DSI  to  HDMI  Bridge  board  supports  automatic  input  video  format  timing 
detection (CEA-861E) and an I2C channel from the APQ8053 allows the user to configure the operation 
of this Bridge Board. The BLSP3_I2C interface is used from the SoC that connects to the Bridge board. 

 

This DSI to HDMI Bridge Board (eI PN# 17_00278_02) supports audio as well. The ERAGON624 uses 
a  single  bit  MI2S_1  interface  from the  APQ8053  chip  which  is mentioned  in  the  below  block.  The 
ERAGON624 carrier should contains the 14 pin HDMI Audio Connector to connect to the Bridge Board.
