Hi Vishal,

Can you elaborate on the application?

The following serializers can be used to support DS90UB681 functionality:

DS90UB941AS-Q1
DS90UB981-Q1

The corresponding deserializer will depend on your video output. Can you specify what output video protocol you require?

We have SW driver support for our products using ALP with a script generation tool and GUI support.

Please download both ALP and ALP-Profile-Update from the site - https://www.ti.com/tool/ALP

Additionally, here is the driver for the 98x family:

Dear Ragav,

I have verified the current configuration of the serializer and deserializer, and the system is driving a Full HD display using the DSI interface over an FPD-Link.

Serializer: DS90UB681
Deserializer: DS90UB688RUR

Could you please confirm alternative part (DS90UB981RTDTQ1) whether this configuration is suitable for our application and deserializer ?

Looking forward to your response.

Thank & Regards,

Hi Vishal,

If the video application is supported with x688, then using the x988 will be a sufficient replacement for the system.

Just to confirm, can you clarify your video resolution settings?

Thanks,
