SC14WAMDECT Module

Wireless Audio Modules for Public Address and Tour Guide Systems

The first DECT based wireless audio solution of its kind

Delivered as a complete and pre-tested wireless audio module, it makes system development as simple as possible. Our module does not require radio frequency (RF) expertise, expensive RF equipment, or extensive resources to move forward with your design and production.

透明声音

Using double slots within the DECT protocol, the microphones operate with a bandwidth of 12kHz. With a latency of ~14msec, this solution is very suitable for these kind of applications.

作为RF技术,DECT非常适合室内和室外应用。雷竞技安卓下载此外,它确保了无干扰通信,允许多个应用程序在不具有频率规划的情况下同时使用和相同的位置使用。雷竞技安卓下载此外,为了简化您的产品创建过程,我们有一个演示系统,可以向您展示性能并提供原理图作为参考。

Public address system functionality

The SC14WAMDECT is a Wireless Audio Module with an integrated baseband, radio transceiver, power amplifier, and crystal to be used for cordless microphone applications in the DECT and DECT 6.0 band. It is a module intended for users who with little or no experience in DECT wish to make a system consisting of 2 microphones, portable parts (PP) and one fixed part (FP) configured as a receiver or integrated into a speaker.

The exact same SC14WAMDECT module is used as both the FP and PP, only configuration of the module will decide the role. The SC14WAMDECT module has been pre-approved for usage in all countries using DECT in the frequency band from 1880 - 1930 MHz as well as for the DECT 6.0 to be used in North America in the frequency band 1910 - 1930 MHz.

Tour guide system functionality

An additional feature of this module is the Tour Guide System functionality, where you can have with one microphone support up to 128 receivers.

This can be headsets for tour guide solutions, which can be used for tours (inside as well as outside), congresses, (multilingual) conferences, bus- and boot tours and theaters, where also speakers can be wirelessly connected to cover the bigger rooms with clear sound.

As the SC14WAMDECT module is fully certified, you do not lose time and money to realize your product.

We are using STM32F412RET with DA7218.
STM32F412RET输出19.2MHz至DA7218 MCLK。
1)Set MIC1_P single-ended input and the signal come from MIC input.
2)Now the I2S DATA of DA7218 has signal output.
3)But the HP_L and HP_R no sound,it always low level.

The sch and the register setting file is attached.

请帮助检查错了。任何罗ce would be appreciated.

Hi Jack,

Could you tell me the MCLK frequency you used?

如果与DA7218一起使用的12.288MHz作为I2S从设备,则可以为HP_OUT启用引用此脚本。

Thanks!

Hi Charlesxue,

Thanks for your reply. Due to the limitation of the platform, it is impossible to output 12.288M MCLK to da7218,

But it can output 19.2M MCLK to da7218, So follow your attachment, I should set 0x91 to 0x03, is it right?

I follow your attachment,and set output 18.432M MCLK to DA7218, because 18.432=(384*sample rate)=384*48K.

But it still no sound from HP.

Hi Jack,

Could you provide i2s format information of platform?

If you could not use 12.288MHz,you need to add configuration in PLL inside of DA7218

Thanks!

我将0x91设置为0x53,PLL Normal,PLL Indiv = 10-20MHz

set 0x90 to 0x81, Master mode (BCLK/WCLK outputs).

But the HP still no sound.

Attachment is DA7218 master I2S mode.
