OVERVIEW
The XE1401SK is composed of two boards: The XE1401SK motherboard and the radio board. The XE1401SK
motherboard carries all necessary components for the XE1401 baseband controller, the XE3006 CODEC, power
management and RS232/USB ports.
The radio board includes a Bluetooth™ radio chip, all required external components to operate it, a flex film
antenna and a SMA connector for an external antenna. Two radio types are supported by the XE1401: Skyworks
CX72303 (formerly Conexant) and Silicon Wave SiW1502.
