2.1 V 至 3.45 V 预编程 无绳 音频 模块
The from Semiconductor is a wireless audio module in MOD88 package. It is a cordless audio module with an integrated baseband, radio transceiver, power amplifier and crystal to be used in cordless microphone applications in the DECT frequency band. This module is intended for users with little or no DECT experience who wish to make a wireless audio system. It can be configured for various audio applications. A public address system has two portable parts PP with two microphones and one fixed part FP configured as a receiver and integrated into loudspeaker. Another application is a tour guide system where one a microphone FP broadcasts to up to 128 receivers PP with an integrated loudspeaker or headset connected. The SC14WAMDECT SF is suitable for both FP and PP usage, a hardware pin selects the function of the module. It is pre-approved for use in all countries that use DECT frequency band as well as the DECT 6.0 frequency band used in North America.
