DS90UB934-Q1: question about pin 43 (MIPI_SEL)

TS Yang

Part Number: DS90UB934-Q1

Dear TI,

At the DS90UB934-Q1EVM user guide page 21, there is a PCB schematic of this EVM.

And it seems that pin 43 is a input pin for MIPI_SEL, and pin 12/11, 19/18, 14/13, 16/15, 22/21, 24/23 support the CSI output interface.

However, at the datasheet of DS90UB934-Q1, the pin 43 is reserved, and must be NC or tied to GND for normal operation.

Which one is right?

Does UB934 support MIPI output or not?

thanks,

Hi steven,

If we implement something like this;

Sensor (MIPI) - 953 (FPD-LINKIII) - Coaxial cable - 934

953 or 934 does not have register contents related to MIPI lane count, clk, image format, bit number setting.

lane number, clk, image format, bit number setting is not necessary?

Please confirm.

thanks,

Yes, you only can check the CSI2 reg. in UB953 to get the data type, ecc, etc.

best regards,
Steven
