PBA RF Module ATM210
5GHz
Wireless Audio Transceiver
REV: 00
4. Introduction
The ATM210 is 5GHz AUDIO TRANSCEIVER that optimized for building point to multi-point digital wireless audio
solutions such as wireless subwoofers and wireless rear speakers in home theater system. This wireless audio
module provides a highly-integrated and flexible wireless audio solution based on the AV5100 SoC.
The AV5100 SoC has the VMI RF protocol, providing a excellent coexistence performance and also provide the
capabilities of world-class wireless audio protocol by supporting increased digital I/O and OTA (over-the air)
signal routing flexibility to accommodate a wide range of wireless audio application. It features low fixed latency,
multiple OTA audio configurations, uncompressed CD quality mono or stereo audio, excellent interference
immunity, and inherent coexistence with WIFI.
The IC contains all the necessary radio transceiver and digital baseband circuitry to form a complete digital
wireless node without the need for external processing as well as including power management and analog
circuitry.
The IC is able to support both the lower and upper bands of 5GHz band RF spectrum, enabling worldwide
coverage.
The highly integrated nature of the AV5100 transceiver IC results in few external components being required for
the ATM210 module design. 2 printed PCB antennas are used to achieve increased range, and to achieve antenna
spatial diversity. The extended-range RF path consists of the antennas, associated tuning components, shield can,
the RF switch, and two baluns, one connected to each of the RF input/output ports on the AV5100 IC.
A 16MHz crystal oscillator generates the AV5100 fundamental system clock used as the basis for all RF and digital
audio clocks.
A 2Mb flash memory chip is used to store the module’s application firmware. The AV5100 is able to boot from
internal ROM upon first power up, which enables programming the flash chip with the application firmware
through USB. In addition, Over-the-air Firmware upgrade capability can be enabled through the application
firmware.
The module can be controlled from an external host device via the I2C Slave or the SPI Slave data interfaces. The
I2C master port allows the module to control other system audio devices such as a sub-woofer amplifier system
without having to add another MCU to the product design.
Up to 9 additional GPIOs are available on the ATM210 module (not including I2C and I2S signals) for implementing
different UI features on the target application.
The ATM210 module is powered from +5V supply input and the internal AV5100 IC is powering the internal +3.3V
output LDO.
The ATM210 module is available in two variations; digital input transmitter or digital output receiver.
There are three available I2S digital audio data inputs/outputs, each of these can be configured to operate as
either a master or a slave – depending on the application, the I2S ports can operate simultaneously as either
inputs or outputs. When configured as slaves, the I2S inputs/outputs can be independently clocked by up to two
external masters. In addition, MCLK can be output from the module to provide a reference clock source to an
external ADC or DAC. MCLK can also be input to the module to provide a reference clock from an external source.
