1. Introduction This document describes the system, operations, and interfaces of the UWB 1port DWA Hub Demo Board. For WUSB application, the dongle is used as the host controller, and connect to wired USB device with a wireless DWA hub. WUSB Application 2. System Description The UWB DWA supports the following functions: Certified WUSB mode Compliant with USB2.0(max. data rate=480 Mbps) Support 53.3M, 80M, 106.7M, 160M, 200M, 320M, 400M, 480Mbps.
should be loaded with proper content by using the Flash utility provided by RealTek. The RF performance can also be tested using the test utility provided by RealTek. One basic clock frequencies are used in the system –66MHz. Some more details of the components are shown in the following sections. The system block diagram is shown below.
2.1.UWB PHY This chip integrates the WiMedia PHY and MAC defined by the standard. This version of chip is packaged in 64-pin QFN form factor. The chip requires 1.5V, 1.32V and 3.3V to operate. High speed USB interface is supported. 2.2. SPI Flash This chip is a serial flash memory with a capacity of 4Mb. It is used by the MAC to store the initialization data and command sequence required by the MAC and PHY on start up. This chip requires 3.3V only. 3. Hardware Interfaces 3.1.

Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. To maintain compliance with FCC RF exposure compliance requirements, please follow operation instruction as documented in this manual. This equipment may only be operated indoors.
7. Coordination Requirements For real application, the transmitter will only be active when communicating with the specific receiver through handshaking, acknowledgement and other mechanisms over the wireless channel. Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
A UWB device operating under the provisions of this section shall transmit only when it is sending information to an associated receiver. The UWB intentional radiator shall cease transmission within 10 seconds unless it receives an acknowledgement from the associated receiver that its transmission is being received. An acknowledgement of reception must continue to be received by the UWB intentional radiator at least every 10 seconds or the UWB device must cease transmitting.
