Abstract

An adapter for a removable data storage device includes a substrate having a signal plane and ground plane. The signal plane includes a socket for receiving a removable data storage device, such as a microSD card. Traces are embedded in the signal plane of the substrate and electrically couple contact pins within the socket to corresponding contacts on the ground plane of the substrate. The traces are arranged as differential pairs which minimizes electromagnetic interference while enabling high data transfer rates and improved signal integrity.
