MIPI D-PHY(v3.0) dl<n>_txrequesths/dl<n>_txreadyhs latency time

Hello team,

 

I would like to know the latency time between the assertion of dl<n>_txrequesths and the assertion of dl<n>_txreadyhs but I can't find this info in the IP documentation.

I need to know what influence this time too.

 

Thanks,

Fabio

Hello Fabio @alfa_hw 

May I know why you need this information ?
Did you see any issue on your HW ? perhaps txreadyhs is not asserted ?

Thanks & regards
Leo

Hello @alfa_hw 

I am assuming that you are designing your own MIPI CSI-2 TX or DSI TX IP yourself now.

Please take a look at Table 1.
If your IP configuration is on the list, your HW should have a similar value with Table 1 value.
If your IP configuration is not on the list, please do simulation.

Your line-rate and LPX configuration will affect this timing latency.

Thanks & regards
Leo
