Overview
The HM500 WHDI Video Source Unit (VSU) is designed to modulate and transmit downstream video and
audio content over the wireless medium and receive a control channel over the wireless upstream. The
modulation uses 18MHz bandwidth and is carried over the 5GHz unlicensed band. Figure 1 displays a
block diagram of the HM500. The inputs to the VSU are digital uncompressed video, digital audio and control,
all via the WHDI connector. I`t has a MIMO design of four wireless output channels and a slow rate data
input wireless channel. The MiniMAC uC i s re spo n si ble for the control and the managem ent.

2.1 AMN2110 WHDI Baseband Transmitter
The AMN2110 WHDITM baseband transmitter chip is the heart of the HM500 WHDI transmitter module. The
AMN2110 interfaces the A/V source through the WHDI connector, and is controlled on board by the MiniMAC uC.
The AMN2110 is based on MIMO technology transmitting through up to four output
channels. Four digital-to-analog converters and on e anal og-to -digital converte r are embed ded wi thin the chip.
The AMN2110 internal PLL accepts an input clock frequency of 40MHz. The input frequency is multiplied and
then used as an internal system clock.
2.2 STM32F103RBT6 Mini-MAC µController
The STM32F103RBT6 microcontroller is based on a 32-bit ARM7TDMI-S CPU, with embedded 128kB highspeed memory. It is used as an external microcontroller for implementing the MAC layer of the WHDI link.
The STM32F103RBT6 internal PLL accepts an input clock frequency of 40MHz.

2.3 MAX2828 5GHz (802.11a) Transceiver
The VSU has four MAX2828 chips embedded in it. The MAX2828 is a single-chip, RF transceiver IC designed
specifically for single-band 4.9GHz to 5.875GHz, OFDM, 802.11 WLAN applications. It includes all the circuitry
necessary to implement the RF transceiver function, providing a fully integrated receive path, transmit path, VCO,
frequency synthesizer and baseband/control interface. Only the PA, RF switches, RF bandpass filters (BPF), RF
BALUNs and a small number of passive components are required to form the complete RF front-end solution.

for the video modem. Future generations of the WHDI modem will use an AMIMON-designed, cost-efficient,
single-chip, integrated RFIC for multiple transmits on the transmitter side and a single-chip, integrated RFIC for
multiple receivers on the re ceive r side.

Overview
2.4 Power Amplifier (PA)
In order to extend the operating range for the HM500, the RF transmitter uses power amplifiers. Each power
amplifier has an output power detector for TPC purposes. Amimon has implemented Anadigics AWL6951 PA on
the HM500.
2.5 Board Connector (WHDITM Connector)
For information regarding the connector specification and pin-outs, see follow i n g section.

EEPROM
The EEPROM is currently a system option, enabling mating and authentication in a multipoint design
environment.
2.7 40MHz Clock Gen
An on-board 40MHz TCXO is connected to the MAX2828 chipsets and the AMN2110 baseband. The clock is
then divided by two by the AMN2110 and supplied to the STM32F103RBT6 uC.

U.S. Regulatory Wireless Notice
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.
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.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.
2006/8/16 v1.0
This device is intended only for OEM integrators under the following
conditions:
1) The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or

As long as 2 conditions above are met, further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met
(for example
certain laptop configurations or co-location with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on the
final product. In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may
