SC14WAMDECT SF Wireless Audio Module FINAL General description Features The SC14WAMDECT SF 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. The module 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 a 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 a headset connected. The SC14WAMDECT SF module is suitable for both FP and PP usage: a hardware pin selects the function of the module. - Pre-programmed and ready-to-use module - Antenna embedded, support for external antennas - High quality audio sampled at 25.6 k Hz - Latency: 14.2 ms (PA mode), 18.3 ms (TG mode) - UART data transfer (up to 1 kbit/s) in TG mode - Access code for secure registration in TG mode - ETSI (DECT) and FCC (DECT 6.0) certified - Japan DECT (J-DECT) pre-certified - Supports 1.9 GHz and 1.7 GHz DECT bands - Receiver sensitivity < -93 d Bm - Transmit power EU: 23 d Bm, USA: 20 d Bm, JPN: 20 d Bm - Power supply voltage: 2.1 V to 3.45 V - Supports Ni MH and Alkaline batteries - Small form factor (19.6 mm x 18.0 mm x 2.7 mm) - Operating temperature range: -40 °C to +85 °C The SC14WAMDECT SF module is pre-approved for Applications use in all countries that use the DECT frequency band, as well as the DECT 6.0 frequency band used in North America. - Public Address System with one or two microphones (transmitter) and one loudspeaker (receiver) - Tour Guide System with one microphone (transmit- ter) and up to 128 headsets...
