(1) For the LPDDR device BGA pad size, see the LPDDR device manufacturer documentation.

(2) A 20-10 via may be used if enough power routing resources are available. An 18-10 via allows for more flexible power routing to the

AM335x device.

(3) Zo is the nominal singled-ended impedance selected for the PCB.

(4) This parameter specifies the AC characteristic impedance tolerance for each segment of a PCB signal trace relative to the chosen Zo

defined by the single-ended impedance parameter.

(5) Tighter impedance control is required to ensure flight time skew is minimal.
