AVMD7520-SWA2

W

+15dBm, U.FL connector, 4 channel digital I/O

ireless HD Audio Module Solution

General Description

The AVMD7520-SWA2module is a
complete radio module solution
containing all the necessary HW and
FW to provide a system-integration­ready, 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.
