1. General Description
The AVMD7540-SWA6 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. 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.

6. Electrical Specifications
6.1. 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.
