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.
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.
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 antenna.
3) For all products market in US, OEM has to limit the operation in the frequency 2412MH,
2438MHz and 2462MHz for 2.4G band by supplied firmware programming tool. OEM shall not
supply any tool or info to the end-user regarding to Regulatory Domain change.
As long as 3 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.

1. General Description
The AVMD7520 module is a complete radio module solution containing all the necessary HW
and FW to provide a system-integration ready, multichannel wireless HD audio solution.
The module is comprised of a AV7540 IC combined with RF front-end circuits (RF PA + balun
+ filter + RF switch), flash memory, crystal, and passive components. It is FCC certified
(modular approval) and ready for operation with U.FL connectors or integrated antennas.
The module 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 edge style using the 36 pin PCIe card edge connection method to save
space and cost in
connecting to the main board.
2. Usage
Install SWA1 module to some CE product, like Speaker, TV …etc, then it will support
Wireless Audio function for these products.
