1. Introduction
This document describes the system, operations, and interfaces of the UWB
USB Dongle Demo Board. Two main applications are supported by this
dongle. One is wireless USB application and the other one is WiNet mode.
For WUSB application, the dongle is used as the host controller, and connect
to wired USB device with a wireless DWA hub. WiNet mode is an IP-based
network communication, and link up the networks by UWB dongles.

2. System Description
The USB Dongle supports the following functions:
n Certified WUSB mode
n WiNet mode
n Compliant with USB2.0(max. data rate=480 Mbps)
n Support 53.3M, 80M, 106.7M, 160M, 200M, 320M, 400M, 480Mbps.
The USB dongle system mainly consists of two main chips – (i) UWB
PHY(RTU7010), (ii) UWB MAC(RTU7300). A serial flash memory(8Mb) is
required to store proper data/commands for the PHY chip and MAC 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. Two basic clock frequencies are used in the system – 12MHz for
MAC and 66MHz for PHY. 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 RF and baseband functions of a UWB PHY defined
by the standard. This version of PHY chip is packaged in 48-pin QFN form
factor. The analog/RF section requires 1.8V and 3.3V to operate. The digital
core operates with 1.5V and the I/O voltage can support a range of 1.8V~3.3V.
2.2.
UWB MAC
This MAC chip is also from RealTek which has a standard MPI interface to
communicate with a standard UWB PHY, as well as a high speed USB
interface to connect directly to a PC. This chip requires voltages of 1.2V and
3.3V.
2.3. SPI Flash
This chip is a serial flash memory from Macronix with a capacity of 8Mb. 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. 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.
This device 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.

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. 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 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.

Realtek UWB dongle User Guide.doc
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.
