[ADV7480] MIPI output status

Category: Software

Hi,

I have some questions about the MIPI output of the ADV7480.

I asked about the MIPI output state in the start-up/power-down sequence

in the following session.

(MIPI output status)

Q1) When the following MIPI-TXA power down processing is executed, will the MIPI output be LP-11?

       I understand that the output does not go from HS to LP state immediately.

        CSI-TXA Map

         1) 94  31  82

         2) 94  1E  00

         3) 94  00  84

         4) 94  DA  00

         5) 94  C1  3B

Q2) In the following MIPI-TXA startup processing,

       I think that it will be in the LP state around the 12th step.

       Is the LP state in this case LP-11?   

        CSI-TXA Map

         1) 94  00  84

         2) 94  00  A4

         3) 94  DB  10

         4) 94  D6  07

         5) 94  C4  0A

         6) 94  71  33

         7) 94  72  11

         8) 94  F0  00

         9) 94  31  82

         10) 94  1E  40

         11) 94  DA  01

         12) 94  00  24

         13) 94  C1  2B

         14) 94  31  80

Best regards.

  • Hi,

    Thank you for your reply.

    I have additional questions.

    Q1) After going into LP mode, will the clock lane go into LP mode as well as the data lane?

          Or will the clock continue to output?

    Q2) If the answer to Q1) is that the clock continues to output and does not enter the LP-11 state,

           I am thinking of setting the MIPI output to Hi-Z.

           Is it possible with register settings?

    Best regards.
