DS90UB933-Q1: does 933 have GPI？

Part Number: DS90UB933-Q1

Hi Team，

It seems that 933 only has GPO. May I ask whether 933 has GPI so that customer could use GPI to transfer camera flash signal to ECU.

As customer feedback, MAX96705 has the GPIO.

Hi Amelie,

Is you customer using RAW12/RAW10? Also what is the paired device?

Thanks,
Sally

Hi Sally,

RAW10 and pair with 934.

It seems that GPO3 could use as input, but as external clock input. Could GPO3 use as the GPIO to transfer PWM signal (25-60Hz) from 933 to 934?

Thanks!

Hello Amelie,

The GPO3 pin can not be used to transfer a signal on the forward channel like this, however if you use the 933 in RAW12 mode, then you can feed in RAW10 inputs from the video, and then the unused extra 2 DIN pins can be used as GPIOs from 933->934. The PWM signal above could be transferred with this method

Best Regards,

Casey
