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.

The CX870-3DS is the same as CX870-3D, except that the RF shield is soldered in place.
