Introduction

The RJ203 is a member of the X20X family of devices. It is an "Ethernet front-end" module that contains 10/100BaseT Ethernet magnetics and a standard RJ45 jack.

The RJ203's magnetics are designed to work with the Davicom DM9000B Ethernet controller. The module's unique patent-pending design minimizes its footprint and allows you to put other components, such as the DM9000B, right 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.

Alternatively, you can use the RJ203 in combination with the EM203 Ethernet module. The EM203 fits right under the RJ203, thus taking no additional space on the host PCB. The EM203's status LEDs remain visible through the translucent face of the RJ203's housing.

The RJ203 can be ordered standalone or in combination with the EM203 module. Click here for detailed ordering information.
