SC14WAMDECT SF01

SC14WAMDECT SF FINAL Wireless Audio Module General description Features The SC14WAMDECT SF is a Cordless Audio Module Pre-programmed and ready-to-use module with an integrated baseband, radio transceiver, power Antenna embedded, support for external antennas amplifier and crystal to be used in cordless microphone High quality audio sampled at 25.6 kHz applications in the DECT frequency band. This module Latency: 14.2 ms (PA mode), 18.3 ms (TG mode) is intended for users with little or no DECT experience, UART data transfer (up to 1 kbit/s) in TG mode who wish to make a wireless audio system. Access code for secure registration in TG mode ETSI (DECT) and FCC (DECT 6.0) certified The module can be configured for various audio appli- Japan DECT (J-DECT) pre-certified cations. A Public Address System has two portable Supports 1.9 GHz and 1.7 GHz DECT bands parts (PP) with two microphones and one fixed part Receiver sensitivity < -93 dBm (FP) configured as a receiver and integrated into a Transmit power EU: 23 dBm, USA: 20 dBm, loudspeaker. Another application is a Tour Guide Sys- JPN: 20 dBm tem where one a microphone (FP) broadcasts to up to Power supply voltage: 2.1 V to 3.45 V 128 receivers (PP) with an integrated loudspeaker or a Supports NiMH and Alkaline batteries headset connected. The SC14WAMDECT SF module Small form factor (19.6 mm x 18.0 mm x 2.7 mm) is suitable for both FP and PP usage: a hardware pin Operating temperature range: -40 C to +85 C selects the function of the module. The SC14WAMDECT SF module is pre-approved for Applications use in all countries that use the DECT frequency band, Public Address System with one or two microphones as well as the DECT 6.0 frequency band used in North (transmitter) and one loudspeaker (receiver) America.
