PCB Layout and Design Considerations for CH7231A

PublishTime：2022-10-20

●The CH7231A is a device targeting the USB Type-C Electronically Marked Cable (E-Marker). The device is designed to follow the USB Type-C Specification 1.2 and the USB Power Delivery Specification Revision 2.0, Version 1.2. The power delivery should support a maximum 5A current. The size of a PCB has a limitation based on E-Marked USB cable assembly
●This application note focuses only on the basic PCB layout and design guidelines for CH7231A, USB Type-C Plug and cable solder line-pads. Since the mechanical design of USB Type-C Plug and the pin sequence of cable solder line-pads are manufactory related, guidelines in component placement, powers upply decoupling, grounding, input/output signal interface are generally discussed in this document.
●The guidelines discussed here are intended to optimize the PCB layout and applications for this product. They are only for reference. Designers are urged to implement the configurations and evaluate the performance of the E-Marked USB cable prior to bringing the design to production.
