[1] D = guaranteed by design; C = guaranteed by characterization; I = 100 % industrially tested.

[2] Connect VDDA(1V8)_D, VDDA(1V8)_P1 and VDDA(1V8)_P2 to the same 1.8 V analog power supply. Use dedicated filters for the three power

pins.

[3] Vgpd represents the ground potential difference voltage. This voltage is the result of current flowing through the finite resistance and the

inductance between the receiver and the driver circuit ground voltages.
