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.
The UWB DWA system consists of single chip – Integrated UWB PHY and
MAC (RTU7105). A serial flash memory (4Mb) is required to store proper
data/commands for the chip. To make the system work properly, the Flash
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.

Certified WUSB
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.

5. 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. Operation outdoors is
in violation of 47 U.S.C. 301 and could subject the operator to serious
legal penalties.
6. 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.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for
help.
CAUTION: Any changes of modifications not expressly approved by
the grantee of this device could void the user’s authority to operate
the equipment.
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. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate
this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
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.
Per FCC regulations, an intentional radiator may only transmit when
communicating with an associated receiver. This continuous transmit mode
is for evaluation purpose only.
In end-user applications, this handled through handshaking,
acknowledgements, negotiation of the communication channel, and other
mechanisms that ensure the transmitter is active when communicating with
a receiver.
