The HM501 is the first generation of WHDI
receiver chip. The HM501 WHDI
transmitter module, presents the ultimate solution for converting any High Definition (HD) system into a wireless
one. This add-on module enables wireless A/V applications that can easily fit into the living room and eliminate
traditional A/V wiring. The ultimate HD video and audio quality and robustness are unmatched by any
other wireless technology and present a true alternative to ca b le. The WHDI system tr ansmits uncompressed video
and audio streams wirelessly and thus simplifies and eliminates system issues experienced with any other
known wireless-based solutions, such as lip-sync, large buffers and other burdens like
retransmissions or error propagation.

Overview
The HM501 WHDI Video Display Unit (VDU) is designed to be at the receiver end of the WHDI downstream. The
HM501 receives wireless downstream transmission, demodulates it and regenerates the video, audio and
control content transmitted by the HM500 WHDI transmitter. The receiver works at the 5GHz unlicensed band.
Figure 1 displays a block diagram of the HM501. It has an MIMO design of five wireless input channels, and one
slow rate output wireless channel, which generates an upstream channel for data content transmissions. The
outputs from the VDU are digital uncompressed video, digital audio and control, all via the WHDI connector. The
MiniMAC uC is responsible for the control and the management.

2.1 AMN2210 WHDI Baseband Receiver
The AMN2210 WHDITM baseband receiver chip is the heart of the HM501 WHDI Receiver module. The
AMN2210 interfaces the A/V source through the WHDI connector, and is controlled on board by the MiniMAC uC.
The AMN2210 is based on MIMO technology receiving up to five input channels. Five analog-to-digital converters
and one digital-to-analog converte r are embe dded within the chip.
The AMN2210 internal PLL accepts an input clock frequency of 40MHz. The input frequency is multiplied and
then used as an internal system cl ock.

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 VDU has five 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.

single-chip, integrated RFIC for multiple transmits on the transmitter side and a single-chip integrated RFIC for
multiple receivers on the receiver side.

Overview
2.4 Power Amplifier (PA)
In order to extend the operating range for the HM501 upstream, the RF transmitter uses a power amplifier. The
power amplifier has an output power detector for TPC purposes. Amimon has implemented Anadigics
AWL6951 PA on the HM501.
2.5 Board Connector (WHDITM Connector)

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 AMN2210 baseband. The clock is
then divided by two by the AMN2210 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

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
