2.0 Usage and Documentation
The AL5721 is a complete, self-contained UWB radio module requiring only +3.3V
regulated power from the host system and providing USB 2.0 interfaces to the host
system for data and the WiMedia association function. The AL5712 is intended to
provide a simple path for a wired USB product design to migrate to a UWB enabled
wireless USB product design.
The AL5721 is a wireless USB certified platform and has received FCC approval as a
Modular UWB transmitter under subpart F of the FCC rules with the FCC ID:
U9YAL5721. The product implementation can apply these approvals to the product
which incorporates the AL5721.
This document provides an outline of the purpose and functionality provided by the
AL5721, complete information for the product system designer is contained in the
Alereon Reference Design Kit (RDK) package consisting of: Schematic diagram, BOM,
and PCB fabrication information including a full Gerber data set.
