Hi,
I have two questions regarding MIPI RESET and XSHUTDOWN signal on CX3 chip as I cannot get any information on this from the product documentation.
1.
How to connect MIPI RESET signal? The datasheet specifies it should be pulled to ground for normal operation. However datasheet also indicates the power up sequence should have MIPI_RESET high along with the RESET pin. The Denobola example has it simply pulled to ground? Is this a problem? Can someone explain what is going on here?
2.
If MIPI_CLK and XSHUTDOWN pins are not used, can they be left floating?
I will appreciate any anwser.

Hi Edo,
1)The MIPI_RESET should be pulled down to ground using 10K resistor (as mentioned in the datasheet).
The CX3 chip will internally drive this pin high during power up. You don't need to connect any external component for the same.
2)By MIPI_CLK do you mean MCLK pin of CX3?
You can leave the MCLK and XSHUTDOWN pins floating when they are not used.
