USB type C 连接器

en cn
The mated connector as defined in this specification for USB Type-C consists of a receptacle mounted on a PCB, representing how the receptacle is used in a product, and a test plug also mounted on a PCB (paddle card) without cable. Note that the test plug is used in host/device TX/RX testing also.

PCBA-paddle card设计要求
The paddle card should use high performance substrate material. The recommended paddle card thickness should have a tolerance less than or equal to ± 10%. The USB SuperSpeed traces should be as short as possible and have a nominal differential characteristic impedance of 85 Ω. The differential pairs should have a minimum pair-to pair separation of 0.5 mm. It is recommended that a grounded coplanar waveguide (CPWG) system be selected 16 as a transmission line method. Use of vias should be minimized. VBUS pins should be bussed together on the paddle card. GND pins should be bussed together on the paddle card. A 10 nF bypass capacitor is required for the VBUS pin in the full-featured cable at each end of the cable. The bypass capacitor should be placed as close as possible to the power supply pad. A powered cable incorporates electronics that requires VCONN power. DFP and UFP supply VCONN whenever there is a resistance less than or equal to Ra between the plug’s VCONN pin and ground.

电性能要求-串扰
Differential Near-End and Far-End Crosstalk between SuperSpeed Pairs The differential crosstalk measures the unwanted coupling between differential pairs. Both near-end crosstalk and far-end crosstalk for mated connector pairs are specified .
Differential Crosstalk between D+/D− and SuperSpeed Pairs The differential near-end and far-end crosstalk between the D+/D− pair and the SuperSpeed pairs in mated connectors should be managed not to exceed the limit shown .

USB Type-C 连接器-公头设计指南 电性能要求-高频测试方法
A USB Type-C to Type-C cable assembly shall be tested using a test fixture with the receptacle tongue fabricated in the test fixture. The requirements are for the entire signal path of the cable assembly mated with the fixture PCB tongues, not including lead-in PCB traces. As illustrated, the measurement is between TP1 (test point 1) and TP2 (test point 2). The test fixture is standardized by USB-IF.

The low level contact resistance (LLCR) measurement is made from the solder tail of the receptacle to the soldering point of the plug (i.e., includes any internal paddle cards, contacts and substrates of the plug and receptacle). See Figure . The following requirements apply to the power and signal contacts: 40 mΩ (Max) initial for VBUS, GND and all other contacts. Maximum change (delta) of +10 mΩ after environmental stresses. Measure at 20 mV (Max) open circuit at 100 mA.

USB Type-C 连接器-公头设计指南 电性能要求-差分特征阻抗
The mated connector impedance target is specified to minimize reflection from the connector. The differential impedance of a mated connector should be within 85 Ω ± 9 Ω, as seen from a 40 ps (20%-80%) rise time. The impedance profile of a mated connector should fall within the limits shown.
The differential return loss measures the differential signal reflection from the mated connector, normalized with an 85 Ω differential impedance.
