(1) The capacitance of the bulk cable is not included in the CCBLPLUG definition. It is modeled as a transmission line.

(2) UI denotes the time to transmit an unencoded data bit not the shortest high or low times on the wire after encoding with BMC. A single

data bit cell has duration of 1 UI, but a data bit cell with value 1 will contain a centrally place 01 or 10 transition in addition to the

transition at the start of the cell.

(3) CRECEIVER includes only the internal capacitance on a C_CCn pin when the pin is configured to be receiving BMC data. External

capacitance is needed to meet the required minimum capacitance per the USB-PD Specifications. TI recommends adding capacitance

to bring the total pin capacitance to 300 pF for improved TX behavior.

(4) Broadband noise ingression is because of coupling in the cable interconnect.
