TDA4VM-Q1: Deserializer DS90UB964-Q1EVM Support for 4meter length FPD Link Cable

Hi Vyom,

The DS90UB964 operation in regard to cable length is determined by channel specification performance for insertion and return loss. We have seen typical cable reaches of 10-15m. With low loss cables, the reach of the cable will be extended whereas, high loss cables may only see success in shorter cables. 

Would you be able to provide insight on the cable type being used? Additionally, what serializer is being used? Is the serializer a custom solution? 

Best,

Zoe

Hello Zoe,

Thanks for the response.

We are using 

Rosenberger FAKRA connectors 4meter length

Sensor: ISX016 (Serializer DS90UB913xx)

Thanks and Regards,

Hi Vyom,

From the initial post, it was stated the camera is brought up successfully with the shorter length cable. What is the lock status on the DS90UB964? This can be read by register 0x4D for each port. 

Additionally, would you be able to share the Margin Analysis results for the DS90UB964 in a good and bad case?

Best,

Zoe

Dear Zoe,

I have tried to dump the value of 0x4D, but getting some garbage value.

Regarding the margin analysis, we will plan that soon and share the results with you.

Thanks and Regards,

Hi Vyom, 

Thanks for the update! Let me know once you get these results. 

Best,

Zoe
