DS90UB940N-Q1: DS90UB940N

Hi Azlum,

What serializer device is the 940N paired with? Are you using the serializer on another custom board or a TI EVM?

Here's the general steps I would suggest:

1. Use the EVM User Guide of the Serializer board as a guide. For example, for the 947, we would refer to this document: https://www.ti.com/lit/ug/snlu140a/snlu140a.pdf?ts=1729715849986&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FDS90UB947-Q1EVM

The SER should be connected to the DES as shown in the document's Typical Configuration. 

2. Download ALP on your PC. This is the GUI you can use to interface with the FPD-Link devices

3. Connect PC to the FPD-Link device. This can be connected on the SER or DES. On a TI EVM you can connect using USB2ANY, or for a custom board (or EVM) you can use I2C with an Aardvark.

4. Use the GUI to set the display timings and enable Internal Pattern generator.

5. If PATGEN works, you can then try with end-to-end video with video input to the SER.

Best regards,

Hello Ikram,

Thanks for the reply.

We are planning to connect DS90Ux949 with custom DS90UB940N-Q1 PCBA by dual link using coaxial cable. Then connect the USB2ANY adapter dongle to J29 on the DS90Ux949 EVM and then test using the ALP Software installed in PC. And FPD Link connection can be checked at “Partner Information” under Information tab in the ALP tool.

Regards,
Azlum
