We are designing an expansion board for the QSB for demo purposes.
In the IMX53QSB schematics (rev. D), in the expansion header description, the DISP0_DCLK signal has a "1.8V" label.
However, it directly connects to the IMX53 IPU DI0_DISP_CLK (pin H4), which according to the datasheet (rev. 4), is on the NVCC_LCD power rail. This is 2.775V.
What is correct, 1.8V or 2.775V?
The same question goes for GPIO_0 (CLK0)?
