AM625: AM625 Display sub system OLDI DPI capabilities.

Hello Oleksiy Kasyan

Thank you for the query.

is this a generic query or do you have a use case that you can provide.

There are number of queries. FYI, one of the constraints for supporting the functionalities is the memory.

Below is a quick summary of what i could find.

I will have to assign to a display expert to support based on your inputs.

Well. I'm developing a product (Computer on Module) that exposes the LVDS and DPI interfaces which can be used in any combination. I would like to know the capabilities of the display interfaces in different combinations.

Hello Oleksiy Kasyan

Thank you.

There are 2 parts to the question

Display sub system capabilities 

Processor capabilities.

Can you confirm you are checking the Display sub system capabilities.

I'm checking the Display sub-system capabilities.

Hello Oleksiy Kasyan

Thank you for the clarification.

Let me review and update you.

Hello Oleksiy Kasyan,

Please refer below inputs.

As I understand from the datasheet, the AM625 CPU has one 2-channel (Dual-link) LVDS interface and one 24-bit DPI (parallel) display interface:
- What is the maximum resolution at a 60Hz refresh rate for the LVDS display when a single LVDS channel is used?
1920x1080 @ 60fps for each display
- What is the maximum resolution at a 60Hz refresh rate for the LVDS display when both LVDS channels are used?
1920x1080 @ 60fps for each display, lower clock speed (compared to the single link)
- What is the maximum resolution at a 60Hz refresh rate for the two LVDS displays connected to the separate LVDS channels?
The LVDS channels (links) work in duplicate mode. Can support 1920x1080 @ 60fps if the display can accept higher frequency the SoC OLDI IP is capable of driving.
- What is the maximum resolution at a 60Hz refresh rate for the 24-bit DPI (parallel) display?
1920x1080 @ 60fps for each display
- Is it possible to use LVDS and DPI displays simultaneously? What is the maximum resolution at a 60Hz in Dual display configuration?
For the display sub system capability this is possible. 1920x1080 @ 60fps for each display
This depends on the use case and the design implementation.

Hello Oleksiy Kasyan,

FYI, i updated the title for searchability.

Hi Kallikuppa Sreenivasa

In the AM625 datasheet, it is mentioned display resolution 2048x1080

For which display? In which mode?

Hello Oleksiy Kasyan,

I assume your query is which of the DSS supports 2048x1080.

Based on the inputs from the expert, i understand the DPI, OLDS-SL and OLDI-DL IP are capable of supporting 2048x1080.
