Solution focus

A clear list of external interfaces, internal connections and cable relationships reduces omissions during project discussion.

Engineering basis

Differential-bus termination and bias depend on topology, cable and transceiver conditions, while USB Type-C includes connector, cable and detection mechanisms. Interface information therefore needs electrical and mechanical context together.

Design focus

List protocol, direction, rate or sampling relationship per interface
Separate board-internal, cable and pluggable connections
Record known termination, shielding, protection and grounding needs

Multiple connector groups and a central connection node

Recommended information

External interface names and purposes
Internal board-to-board connections
Cable, socket and orientation notes

Handoff and verification

Interface and pin-definition table
Connector and cable mating information
Protocol, termination and protection open items

Next collaboration step

After the information for interface and connection planning is confirmed, align the functional, interface, material, assembly and revision information before the next solution discussion.
