USB Type-C Connector & Cable Test

The Tiniest of Connectors Looks More Like A Complex Backplane System!


The USB Type-C connector represents a dramatic development in the consumer electronics industry. It provides a compact, reversible, and multi-protocol interconnection and powering scheme that enables extremely high bandwidth. The technological advancements in the Type-C connector make it appear more like a complex backplane system, and this creates significant test challenges.

Introspect’s SV1C is ideally suited for testing Type-C connectors and cables!

Large Lane Count

The reversible design of Type-C connectors is enabled by replication of the high-speed tracks on opposite sides of the printed circuit board. Additionally, the Type-C connector includes USB 2.0 lines as well low-speed custom pins. This means that full test coverage of a Type-C system requires a large number of pattern generator and analyzer lanes, and this is naturally enabled in Introspect’s Personalized SerDes Testers.

Auxiliary Voltage Source

The Type-C connector includes VBus pins for high current power delivery. From a test perspective, the ability to provide a regulated power supply to these pins is highly desirable. In sticking true to its “smart phone of test and measurement” design paradigm, the SV1C includes an auxiliary power supply that can be used for this purpose.

Custom Control Pins

To enable multiple protocols and to achieve reversible orientation detection, the Type-C connector contains various digital pins and even pull-up and pull-down sense mechanisms. These are best addressed with a digital vector test system capable of driving high, low, or tri-state as well as sensing voltage levels. The SV1C includes built-in high-speed Vector Tester IP that is ideally suited for testing these innovative Type-C custom control solutions.
