The USB Type-C is a new small reversible-plug connector for USB 3.1 devices. The type-C plug will be used at both the host and device side, replacing multiple Type-B and Type-A connectors and cables with a future-proof standard similar to Apple’s Lightning and Thunderbolt. The 24-pin double-sided connector provides four power/ground pairs, two differential pairs for USB 2.0 data bus, four pairs for high-speed data bus, two ‘sideband use’ pins, two configuration pins for cable orientation detection, dedicated biphase mark code (BMC) configuration data channel, and +5 V power for active cables.
