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.
