1. General Description
The AVMD7540-SWA5 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 and ready for
operation with U.FL connectors. 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.

5.1. Absolute Maximum Ratings
The Absolute Maximum Rating (AMR) corresponds to the maximum value that can be applied without leading
to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Absolute Maximum
Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at
or beyond these limits. Device functional operating limits and guaranteed performance specifications are given
under Electrical Characteristics at the test conditions specified.

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.

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-SWA5". 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.
