Hi team,

I have two questions.

1) In RAW mode(paired with 913A), does the CSI2 output have line start short packet and line end short packet?

2) UB936's output is not 8b9b line coded, right?

Hello Atsushi-san,

1. No, there is no line start or line end short packet. Those packets are optional in the CSI-2 spec and our device does not generate them in RAW mode

2. What output are you referring to here? The CSI-2 output? FPD back channel?

Best Regards,

Casey

Casey-san,

Thank you for your prompt reply!!

I've understood about Q#1.

For Q#2, I questioned about CSI2 output. D-PHY spec has 8b9b line cording option.

Hello Atsushi-san,

The DPHY transmitter does not use the 8b9b mode
