1 Differential capacitance is measured between the VIN+x and VIN−x pins (x = A, B).

2 AVDD3 current changes based on the Buffer Control 1 setting (see Figure 46).

3 Parallel interleaved LVDS mode. The power dissipation on DRVDD changes with the output data mode used.

4 Standby can be controlled by the SPI.
