General Description
The AVMD7520-SWA2module is a
complete radio module solution
containing all the necessary HW and
FW to provide a system-integration-
ready, multichannel wireless HD audio
solution compatible with the AM2G and
AAL wireless audio system.
The module is comprised of an AV7520
IC combined with RF front-end circuits
(RF PA + balun + filter + RF switch),
flash memory, crystal, and passive
components. It is an FCC modular
certified solution with RF connectors for
connection to external antennas. The
module also provides a convenient set
of digital I/O interfaces for digital audio
through an I2S port, host MCU control
through an SPI or I2C interface and
optional GPIO for various control and
indicator functions.
The module is a card slot style using the
36 pin PCIe card edge pin arrangement
to save space and cost in connecting to
a main system board.

FCC Statement
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.
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.
This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna or transmitter.
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.

IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC compliance requirement
of the end product, which integrates this module.
20cm minimum distance has to be able to be maintained between the antenna and the users for the host this module is
integrated into. Under such configuration, the FCC radiation exposure limits set forth for an population/uncontrolled
environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this
equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm separation with the
antenna while this end product is installed and operated. The end user has to be informed that the FCC radio-frequency
exposure guidelines for an uncontrolled environment can be satisfied. The end user has to also be informed that any
changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this
equipment. If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to
be available in the users manual: This device complies with Part 15 of 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.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains TX FCC ID: NKR-SWA2". If the size
of the end product is larger than 8x10cm, then the following FCC part 15.19 statement has to also be available on the
label: This device complies with Part 15 of 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.
