1. Introduction

The ATM100 module offers customers fast time to market with a mono, or stereo, wireless audio connection. The module

is optimized for low-cost, high-quality, easy-to-use wireless audio solutions for wireless subwoofer or wireless rear speaker

applications.

Avnera’s proprietary wireless system takes a new approach to wireless audio. The wireless protocol was designed from the

ground up and delivers uncompressed mono or stereo audio, with fixed latency over the air, without interference issues,

and with industry leading WiFi coexistence – even at close proximities to a WiFi device.

Avnera-enabled wireless modules offer a low-touch, easy-to-integrate wireless audio solution and enables fast time to

market by eliminating concerns about compliance, antenna tuning, and board optimization.

Modules based on Avnera’s AV6210 silicon provide breakthrough wireless audio functionality with fixed low-latency

point-to-point transport of uncompressed mono/stereo PCM audio data supporting a wide range of input sample rates. A

single I2S digital audio port is used for the module audio input/output.

ATM100 3. General Function The ATM100 module is available in 2 variations; digital input transmitter module or digital output receiver module. There is a separate I2S port for digital audio input and output functions and either of these can be configured to be a master or a slave – only the input or output port can be active at any time. In addition, MCLK can be generated from the module, or input to the module as required by the system application.

ATM100 Typical Sub-Woofer Implement A simple low cost implementation of a sub-woofer product design is shown in Figure 2. The sub amplifier consists of a PWM chip plus an output stage device, but no external MCU is required as the ATM100 RX module performs the control function using the I2C master communication port in conjunction with multiple GPIOs. +5V power and an optional reset signal are supplied to the ATM100 RX module and I2C slave communication can be used to control the module if required.

ATM100 I2S Out Port I2C Slave Port I2C Master Port GPIOs is an I2S slave. CMOS 3.3V logic levels are used for all I2S signals. 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.

ATM100 6. Notice FCC, IC Statement This AUDIO TRANSCEIVER has been granted modular approval for mobile applications. OEM integrators for host products may use the module in their final products without additional FCC / IC (Industry Canada) certification if they meet the following conditions. Otherwise, additional FCC / IC approvals must be obtained.  The host product with the module installed must be evaluated for simultaneous transmission requirements.
PAGE 11
ATM100 Device Classifications Since host devices vary widely with design features and configurations module integrators shall follow the guidelines below regarding device classification and simultaneous transmission, and seek guidance from their preferred regulatory test lab to determine how regulatory guidelines will impact the device compliance. Proactive management of the regulatory process will minimize unexpected schedule delays and costs due to unplanned testing activities.
PAGE 12
ATM100 Simultaneous Transmission Evaluation This module has not been evaluated or approved for simultaneous transmission as it is impossible to determine the exact multi-transmission scenario that a host manufacturer may choose. Any simultaneous transmission condition established through module integration into a host product must be evaluated per the requirements in KDB447498D01(8) and KDB616217D01,D03 (for laptop, notebook, netbook, and tablet applications).
