1 Introduction

This document describes the system operation of P0029B – a one-port DWA (Device
Wire Adapter), as well as driver installation and the use of control software.

2 System Operation

2.1 General Description

P0029B is a one-port DWA to which a USB device can be attached. It converts the
wired interface of the device to Wireless USB over UWB (Ultra-wideband).

2.2 System Block Diagram

The following figure shows the system block diagram of P0029B. It accepts +5V
from a power adapter and converts it to various voltages required by the MAC-PHY
chip. Only one crystal is used in the system, which is of 66MHz. The system is
designed to support both BG1 and BG3 UWB bands as defined in the WiMedia
standard.
