Part Number: SN65DSI84
Other Parts Discussed in Thread: SN65DSI83EVM

Tool/software:

Hello Team,

We have few follow-up queries as mentioned below.

Could you please help on this as well?

We are planning to use the SN65DSI84ZXHR in our design and have a few software and hardware-related queries for the bring-up and development process:

1. Single-Channel DSI to Two Single-Link LVDS Use Case

We aim to implement a single-channel DSI to two single-link LVDS use case using the SN65DSI84ZXHR. Could you confirm if there are any software limitations or known constraints with this setup? Or can only dual link lvds panels supported (In SN65DSI84 datasheet we referred to Figure 8-1. Typical 1920 x 1200 WUXGA 18-bpp Panel Application)?
Additionally, please provide the required driver files or any reference software available for this chip.

2. SN65DSI83EVM Board Validation

For development, we plan to procure the SN65DSI83EVM evaluation board. Could you share a list of panels validated with this platform, along with any recommendations for compatible panels that have been tested and optimized?
DSI Tuner Software and Validated Configurations

3. Please provide the procedure to download the DSI Tuner software used for configuration.
Additionally, if possible, kindly share validated .dsi configuration files for commonly used panels to expedite the development process.

4. Validation on Qualcomm Processors

Has the SN65DSI84ZXHR been validated on any Qualcomm processors? If yes, please share details on the compatible processors and any available reference designs or implementation notes.

Your prompt assistance with the above queries will greatly help streamline our development efforts.

The only constraint is to keep the timings consistent between the DSI signal and the LVDS output.

DSI Tuner Software and Validated Configurations

We do not have an extensive list of panels used. However, we are able to support any panel that is within the resolution limits of our part, and supports either VESA format 1 or format 2, as laid out in the datasheet.

The download files can be found in the above link. You will need java to run the DSI tuner tool.

This device has been used successfully on QUALCOMM processors. We do not have a list of processors used before. One item to consider in your deign is to make sure that the initialization sequence and the video start and stop sequence are properly followed.

Thanks for the response:

We have few more questions:

1. Could you please point out to the panel used for the below application:

https://www.ti.com/lit/gpn/sn65dsi84 (section 8.2 Typical Application)

2. Is both the modes are supported from SW side?

In the case of Single DSI Input to Single-Link LVDS panel can be connected to either CHA or CHB? depends on config?

3. Could you please suggest for the panels to be used for below use case.
Single DSI Input to Single-Link LVDS
Single DSI Input to Dual-Link LVDS

Hi,

1. Could you please point out to the panel used for the below application:

https://www.ti.com/lit/gpn/sn65dsi84 (section 8.2 Typical Application)

*** The LCD part number is LG PHILIPS LP181WSA(TL)(N1).

2. Is both the modes are supported from SW side?

In the case of Single DSI Input to Single-Link LVDS panel can be connected to either CHA or CHB? depends on config?

*** Both modes are controlled from the SW using the LVDS_LINK_CFG bit. In LVDS Single-Link configuration, Channel A output enabled and Channel B output disabled.

3. Could you please suggest for the panels to be used for below use case.
Single DSI Input to Single-Link LVDS
Single DSI Input to Dual-Link LVDS

*** We do not have a specific recommended panel. Panels will be support as long as the resolution is 60-fps WUXGA 1920 × 1200 Resolution at 18-bpp and 24-bpp Color, and 60- fps 1366 × 768 Resolution at 18-bpp and 24-bpp.

Thanks

David
