Dear TI Experts,

I am now using DA90UB953 + DS90UB954, and when I test for a long time, their will be a frame drop, And when collecting images on a car,the frame drop situation is more frequent~

The data flow we test using 953 and 954:

when their is some error in the data flow：

                    register                   value

954                  0x7a                       0x02

954                  0x7b                       0x02

954                  0x37                       0x03

953                  0x52                       0x65

 

when anything is OK in the data flow：

                     register                     value

954                  0x7a                       0x00

954                  0x7b                       0x00

954                  0x37                       0x00

953                  0x52                       0x45

 Can you help to find out what's wrong with DS90UB954?thank you~

 

Another question,About POC Circuits, do we have 12V output voltage,o.6A current reference design?Or do we have documents describe how to design POC circuits?

    Generally, your link has high bit error between UB953 and UB954. You can check:

    1. PoC network design, and PoC voltage stability?

    2. UB954's lock detection indication through pin or reg (please read UB954's d/s on lock status register)

    3. Analyze the link fidelity, such as transmission channel SI, supply noise, etc.

    You can visit www.ti.com/FPD-Link on high speed link knowledge and PoC design skill.

    regards,
