- Qualcomm Linux display supports the third-party DSI-to-HDMI bridge chip
extensions. The basic configurations required to integrate the bridge
chips are explained as follows:

**Figure : Bridge chip configuration**
## Reference bridge chip configurations
The LT9611uxc DSI-to-HDMI bridge chip is used in the reference platform. For
more information on the LT9611uxc DSI-to-HDMI bridge chip, see the
Lontium semiconductor datasheet.
To use the reference DSI-to-HDMI bridge chip, see the [.dtsi](https://git.codelinaro.org/clo/le/platform/vendor/opensource/display-devicetree/-/blob/display-kernel.qclinux.1.0.r2-rel/display/dsi-panel-ext-bridge-1080p.dtsi?ref_type=heads) file.
The following table lists the configurations that are required to integrate bridge chips.
