3.5 Display Interface

The 96Boards specification calls for an HDMI port to be present on the board.

The Renesas RZ/G2L&RZ/V2L doesn't include a built-in HDMI interface. The Renesas RZ/G2L&RZ/V2L deploys the

built-in MIPI-DSI 4 lanes interface as the source for the HDMI output. A peripheral DSI to HDMI Bridge (U25, Analog

Devices ADV7533) performs this task and it supports a resolution from 480i to 1080p at 30Hz. While the ADV7533

supports automatic input video format timing detection (CEA-861E), an I2C channel from the Renesas RZ/G2L&RZ/V2L

allows the user to configure the operation of this bridge. It is RIIC1_I2C interface from the SoC that connects to the

bridge.

This bridge supports audio as well (meeting the 96Boards requirements to provide audio via HDMI). The Renesas

RZ/G2L100&RZ/V2L100 uses a single bit I2S1 interface from the RZ/G2L&RZ/V2L for this task.

Please note that the 96Boards specification calls for a MIPI-DSI interface to be routed to the High Speed Expansion

connector. Since the RZ/G2L&RZ/V2L has only one MIPI-DSI interface. A muxing device (U24, FSA644UCX) is being use

on the board. Only one interface, HDMI, or the Expansion MIPI-DSI can be active at a given time. The controlling signal

is named

'P4_1_DSI_SW_SEL'. When this signal is logic low, '0', the MIPI-DSI is routed to the High Speed Expansion connector.

When

'P4_1_DSI_SW_SEL' is logic level high, '1', the MIPI-DSI is routed to the DSI-HDMI Bridge. This design

assigned the 'P4_1_DSI_SW_SEL' function to P4_1/SCIF2_RXD/MTIOC7B.

The 96Boards specification calls for a MIPI-DSI implementation via the High Speed Expansion Connector.

Renesas RZ/G2L&RZ/V2L implemented a four-lane MIPI_DSI interface meeting this requirement. More information about

The
