Block diagram MIPI-CSI / TQ Camera Interface
The interface is already used on the MB-SMARC-2 and other TQ boards. Functions have been added to the interface in
coordination with TQ EMB.

300 mA (2x150 mA) is budgeted for the TQ camera adapter on the 5 V level. The current consumption has been determined on
the basis of the worst-case power consumption of the reference camera "Li-Apollo-adp-IMX185" from Leopard Imaging Inc of
0.63 W. If higher power is required for the connected cameras, this must be subtracted from the power provided at the starter kit
headers.
The components under the area for the adapter board must not exceed a height of 2 mm!

Mini PCIe
A mini PCIe card slot is realised on the MBa8x. This is connected to the PCIe0 interface. The interface is wired with all signals
provided by the standard (e.g. USB, I2C, PCIe). The clock is generated externally from a central location.
