Method for an integrated RJ-45 over two mini-USB type-B receptacles

Disclosed is a method for an integrated RJ-45 over two mini-universal serial bus (mini-USB) type-B receptacles. Benefits include improved support for future technologies.

Background

        � � � � � Several initiatives exist to shrink the overall size of desktop computers. Most initiatives require changes to various components. Conventionally, the standard Magjack, which is an� integrated RJ-45 over two USB type-A connectors, is used for this function. It is over 30-mm tall and limits the design of small form-factor systems (see Figure 1).

        � � � � � An RJ-45 is a standardized registered jack. Universal serial bus is a standardized serial transfer protocol. Applications designated as 10/100 BaseT support Ethernet transfers of 10 and 100 megabits per second using unshielded twisted pair cabling and RJ-45 connectors. Applications designated as 10/100/1000 BaseT support Ethernet transfers of 100, 100, and 1000 megabits per second.

General description

        � � � � � The disclosed method is a compact version of the Magjack integrated local area network connector used on conventional board assemblies.

        � � � � � The key elements of the method include:

•        � � � � Modular jack

•        � � � � Two mini-USB type-B receptacles

•        � � � � Two indicator lights (optional)

•        � � � � Printed circuit board mounted with magnetics for 10/100/1000 BaseT applications, all contained within the same housing

Advantages

        � � � � � The disclosed method provides advantages, including:

•        � � � � Improved support for future technol...
