1. Overview
Linkplay Wi-Fi Audio module - A88, is our 3rd generation smart audio modules developed to be used in the
connected speaker, sound bar and other connected audio devices. It integrates the low power Broadcom
BCM43455 Wi-Fi/BT chip and Amlogic A111 application processor. A111 is an advanced application processor
designed for connected audio applications. It integrates a powerful CPU subsystem, advanced multi-format audio
processing unit, a secured running environment and all major peripherals to form the low power audio AP.
The main system CPU is a quad-core ARM Cortex-A5 CPU with 32KB L1 instruction and 32KB data cache
for each core and a large 512KB L2 unified cache to improve system performance. Each Cortex-A5 CPU can run
up to 1.5GHz and has a wide bus connecting to the memory sub-system. The main CPU handles all operating
system, networking and user-interface related tasks. The audio processing engine (APE) is based on ARM®
NEONTM general-purpose SIMD architecture which works seamlessly with main CPU to accelerate the
multimedia processing algorithms, enhancing the user experience. It is able to decode all major audio formats up to
192KHz high resolution including MP3, AAC, WMA, RM, FLAC, OGG, etc and with the flexibility to support
future audio standards. A111 also integrates all standard audio input/output interfaces including I2S, PCM and
S/PDIF audio input/output for different applications.
A88 module supports IEEE 802.11 a/b/g/n/ac 2.4GHz and 5GHz. It also supports BT4.2 with EDR and BLE.
A88 module also provides USB, I2S, I2C, PWM, SPI, UART etc. interfaces.
The firmware is fully compatible with Apple AirPlay and digital living network alliance (DLNA) streaming
standards. It supports Hi-Fi audio up to 192KHz, 24-bit with most popular audio formats. It supports multi-room
and multi-channel audio streaming with perfect synchronization.
With this module, you can play the music on your speaker wirelessly from iPhone, iPad , iPod touch, Android
devices or PC. More important, it enables the traditional speaker system to become the Internet enabled device
through the wired or wireless connection provided by the module. Thus, you could freely playback any Internet
audio contents such as music, podcast, radio or either the accompany audio in the movie directly from the Internet.

FCC Statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept
any interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be
installed in any portable device.
FCC Radiation Exposure Statement
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. This modular must be installed and operated with a minimum distance
of 20 cm between the radiator and user body.
If the FCC identification number is not visible when the module is installed inside another device,
then the outside of the device into which the module is installed must also display a label
referring to the enclosed module. This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID: 2ANOG-A88 Or ContainsFCC ID: 2ANOG-A88”
When the module is installed inside another device, the user manual of the host must contain
below warning statements;
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause
undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions
as described in the user documentation that comes with the product.
Any company of the host device which install this modular with Single modular approval should
perform the test of radiated emission and spurious emission according to FCC
requirement, Only if the test result comply with FCC equirement, then the
host can be sold legally.
