1 Introduction

The CX-series module is a single-board networked media player module, based on SMSC’s DM870A and DM875
media processors, and enables fast product developments with Ethernet, USB and optional WiFi connectivity. The
module connects to standard legacy components in various audio, video/LCD and control formats.

Note: Please note that the Apple Authentication Coprocessor will not be provided on the CX module. The Apple Authentication
Coprocessor should be provided on the product motherboard, connected to the SDA, SCL signals from the CX module.

Note: Shaded rows indicate Custom or Obsolete configuration - NOT TO BE USED FOR NEW/STANDARD MP DESIGNS.

* Connector on board, but requires board modification to enable the connector.
+ The position of the X in the One Ant. column indicates that there is one external antenna connector provided. The position of the X

in the Two Ant. column indicates that there are two external antenna connectors provided. Do not use a module which has two
external antenna connectors with only one external antenna connected. Leaving one antenna socket open will degrade WiFi
performance. SMSC recommends always using modules with two external antennas for best performance.
