DS90UB926Q-Q1: Configurations when starting-up the device

Part Number: DS90UB926Q-Q1

Hello, Team,

I have two questions:

  1. We would like to know what needs to be configured (i.e. what kind of parameters needs to be set) when the device starts up.
  2. How long does it take from power-on to outputting an image to a screen? Give me answers in seconds/milliseconds.

Thanks!

Best Regards,
Masaru

    Hello Masaru,

    1) This depends on your use case. Normally for the basic function, you just need to set-up the MODE_SEL pin, IDx pin correctly.

    There are other features that you may want also to use, such as Dithering, White balance, SSCG, Oscillator outputing or PCLK edge select features.

    2) I can't give you an answer to this question because this depends on different parameters, such as stable LOCK, stable AEQ, enabling the Output, Output sleep state pin... etc. Nevertheless, please refer to the timings in the Switching Characteristics table (7.10) on pages 13 and 14. Also figures 5 and 7 gives you clarifications to your question. 

    You may measure this time on your own application for geting the exact answer.
