DS6800W Airplay Dock Instruction

DS6800W is a USB/MP3-IN with Airplay dock product.
The main work principle can divided into 4 parts:the control part,the power part, the audio part,
the Airplay part.
The control part takes charge of the control of the product which uses LM38800 as its MCU. The
MCU takes charge of some parts including Keys,LED,power management,Software upgrade,bus
mastering and so on. The audio source coming from Ipod,iPhone,iPad via USB scoket is ARM
decoded by the D/A(PCM1808).The ARM system also control the Airplay part(DM870) by Apple
certificate CP2.0B IC.
The main power of the system using 20V power supply by DC/DC adapter,power control
IC(TPS54286) and IC(AMS1117)is transformed to several type as20V, 5V,3.3V, 1.2V,1.8V etc.
All of the audio signals produced by the audio processor IC(CS48520), then these audio signals
flow to the control IC(STA339BW) ,finally connecting with the tweeter and woofer speakers.
The Airplay part used BridgeCo CR870-2I,main IC is DM870.
