iMX6Q Voltage of CSI parallel pins

[herveschmitt]

We didn't find information on the voltage constraints of PIXCLK, HSYNC, VSYNC, DATA[0..7] in the IMX6DQIEC.

We checked the signals using an OV5652 module (natively supported by the Freescale BSP) that have an amplitude of 3.3V.

We are now working on a camera module powered with 1.8V and wonder if it can work "as is" or require some level shifters 1.8V -> 3.3V.

TIA.

HI Herve

NVCC_CSI is voltage domain of PIXCLK, HSYNC, VSYNC, DATA[0..7] in the IMX6DQIEC,

so it is necessary to power it with 1.8V for operation with sensor with 1.8V levels

Best regards
