Part Number: DS90UB933-Q1

Hi Team,

1. Now I Use DS90UB933 as camera module,I'm currently using 8-bit data. ,Attached is my schematic diagram, please help to review it?

2. The another question is that need add another s_ERR inpuBYD360_Block Diagram_V01.pdft alarm signal to the TI933,HowBYD360_Ti933_v01_sch.pdf to add?

Hi Ian,

I can review your schematic. I will return with comments within ~1 week.

And for your second question, could you elaborate a bit more? Do you mean you want to send an alarm signal from the DES->SER->Camera?

Best,

Hi Justin,

Thank you for your support.

Error interrupt signal generated by sensor，I want to use GPIO transparent interrupt signal, through the Des terminal output GPIO status to determine whether it is an error interrupt signal? But 933 only has GPO output but no GPI input. What should I do?

Hi Ian,

What is the paired deserializer device?

This would help me get a better idea of a possible solution.

hi Justin，

The following diagram，There is no paired deserializer device .

Hi Ian,

The UB933 serializer needs to be connected to a compatible deserializer device.

If the deserializer has a parallel interface (such as the 934), then it is possible to feed the s_ERR signal into DIN[8] in the serializer. The s_ERR signal will be sampled at the PCLK frequency and transferred to ROUT[8] in the deserializer. This is only possible since the device is in 10-bit mode, but only 8-bits are needed to transfer video data. The only risk is that jitter on the PCLK frequency will affect the sampling of the s_ERR signal.

If the deserializer has a CSI-2 interface (such as the 954), then there is no option to send s_ERR to the DES terminal.
