RJ203 Jack/Magnetics Module

An isometric render of the RJ203.

The RJ203 is an "Ethernet front-end" module that contains 10/100BaseT Ethernet magnetics and a standard RJ45 jack. The module's magnetics are designed to work with Davicom's DM9000B Ethernet controller.

The unique, patent-pending design of the module minimizes its footprint and allows you to put other components required on your host board under the RJ203, thus saving valuable host board space. Moreover, the translucent housing of the RJ203's face enables you to place status LEDs directly on the host board and have these LEDs visible through the front face of the RJ203.

There are two ways in which you can utilize the RJ203 in your design:
