Product Description


SIP AUDIO MODULE  SIP2103T

SIP2103T network audio module is a general independent SIP audio function module, which can be easily embedded into OEM products. 
The module encodes and decodes the SIP protocol and RTP audio stream from the network.
The module supports a variety of network protocols and audio codec protocols, and can be used for VoIP and IP paging, high-quality music streaming media playback and other applications.
SIP2103T also provides two serial ports and eight digital I / O, allowing users to control through programs.


Characteristic


Standard RJ45 network interface, provide firmware online remote upgrade;

Based on ARM + DSP architecture, high-speed industrial chip is adopted, and the start-up time is less than 1 second;

Multiple IO interfaces are provided to enrich the module functions;

It has the function of controlling the serial port and can control the work of the module;

It has the function of universal serial port and can realize the function of transparent data transmission;

It has audio line output port, which can be connected with active speaker for amplifying;

With audio line input port, it can be connected with active microphone for intercom.

Structure


SIP2103T uses a 400MHz ARM processor architecture and a professional bidirectional audio codec codec. The arm processor isresponsible for data transmission, user command analysis and execution, and power amplifier interface control. The professional
audio codec is responsible for audio input and output. Its internal structure is as follows:




Its appearance structure is as follows:




Application




Outdoor loudspeaker
Desktop walkie talkie
intercom terminal


PLAY
The network audio equipment can receive the audio stream from the network, and convert it into an analog audio signal for output after being decoded. The figure below is a standard playback application scenario.

The SIP2101T/SIP2103T network audio module is used as a playback terminal, and only needs to increase the power supply and external power amplifier. It can be used as a device alone, or integrated in other audio equipment (power amplifier, or active speakers, etc.) to make it a network audio playback terminal.




INTERCOM
SIP2103T can be used in a two-way SIP intercom system





The broadcast intercom host can use our company's broadcast system control software, broadcast equipment, network microphones, etc., or use the SIP server prepared by the user.
This VoIP Telephone Circuit is ideal for access system, railway applications, tunnels, highways, campus, parking lot, power stations, oil&gas station, marine applications, underground mining, retail banking, clean rooms, firefighter, taxi, industrial, prisons, parking-lots, power stations, chemical plants, etc.
