Display Interfaces

4.1.1

MIPI-DSI

The UCM-iMX93 MIPI-DSI interface is derived from the four-lane MIPI display interface available
on the i.MX93 SoC. The following main features are supported:

Compliant with MIPI DSI specification v1.2 and MIPI D-PHY specification v1.2

Maximum data rate per lane of 1.5 Gbps

Maximum resolution ranges up to 1920 x 1200 p60
The following table below summarizes the MIPI-DSI interface signals.

LVDS Interface

UCM-iMX93 provides one LVDS interface derived from the i.MX93 LVDS display bridge. It
supports the following key features:

Single channel (4 lanes) output at up to 80MHz pixel clock

Resolutions of up to 1366 x 768 p60 or 1280 x 800 p60
The table below summarizes the LVDS interface signals.
