User Manual
1. Introduction
The ATM200 is a 5GHz wireless audio transceiver module offering point to multi-point digital wireless audio solutions
such as wireless subwoofers and wireless rear speakers and in home theater system.
The module incorporates AV5100 SoC (System-on-chip) with Avnera’s proprietary 5GHz wireless audio protocol 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 AV5100 SoC contains all the necessary radio transceiver and digital baseband circuitry to form a complete digital
wireless node without external processing as well as including power management and analog circuitry to operate it.
The module integrates all feature necessary to complete a wireless link including wireless audio IC, power amplifier (PA),
flash memory, printed diversity antennas, FPC connector and passive components. It provides better extended wireless
range with external PA and user interfaces through 24pin FPC connector.
The ATM200 module is certified to FCC and CE standards.

Description
+5.0V supply
The ATM200 module is configured to accept a nominal +5.0V supply.
Reset
Active low reset input. This pin is driven from an open collector/drain device such that it can be
pulled to ground for the active reset state but, when released, must go to a high impedance state.
This pin should not be actively driven high, as the AV5100 internal reset circuit will not operate
correctly.
I2S In Port
The I2S input port can be configured as a master or slave. Consequently BCLK and LRCK can
be either inputs or outputs. In addition, MCLK can be sourced by the module. Since the AV5100
IC contains a sample rate converter, MCLK is not required to be supplied to the module when it
is an I2S slave. CMOS 3.3V logic levels are used for all I2S signals.
I2S Out Port
The I2S output port can be configured as a master or slave. Consequently BCLK and LRCK can
be either inputs or outputs. In addition, MCLK can be sourced by the module. Since the AV5100
IC contains a sample rate converter, MCLK is not required to be supplied to the module when it
is an I2S slave. CMOS 3.3V logic levels are used for all I2S signals.
I2C Slave Port
The I2C slave port can be used for external host communication and for module testing. It is
assumed that external pull up resistors are connected at the I2C master communicating with the
module.
I2C Master Port
The I2C master port is used to communicate with external audio devices such as a sub-woofer
amplifier or rear speaker. It is assumed that external pull up resistors are included on the
application board.
GPIOs
3.3V CMOS logic level GPIOs available to connect to other devices, or to use as UI supporting
GPIOs for LED and button support. All supported GPIOs can be configured as outputs or inputs
with configurable pull-ups/pull-downs.
ATM200
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.
The hardware for the audio input (transmit) and audio output (receive) versions of the module is identical and only the
firmware loaded onto the module determines its function.
The highly integrated nature of the AV5100 transceiver IC results in few external components being required for the
ATM200 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,
RF power amplifier (PA) 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 ATM200 module (not including I2C and I2S signals)
for implementing different UI features on the target application.

5. Electrical Specifications
Absolute Maximum Ratings
Absolute Maximum Ratings (AMR) are stress ratings only. AMR corresponds to the maximum value that can be applied without leading
to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may
cause permanent damage to the device.
Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Range” is
not implied. Exposure to absolute-maximum-rated conditions for extended periods may adversely affect device reliability.
Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test
conditions specified.
