FM1182 Datasheet | Forte

feature allows FM1182 to be used in portable wireless hands-free devices. The industry leading echo cancellation will enable speakerphone functions to be .. added to Bluetooth headsets and other small form-factor devices. With an integrated USB audio interface, designers can minimize BOM costs in offering a USB speakerphone. Also, with the FM1182, any PC or monitor can bee a hands-free munication device allowing users to run PC telephony applications. The FM1182 can also convert traditional telephones into USB telephones that will enable users to connect to the PC as another means of munication. Application Summary: - Portable Bluetooth device (mobile phone, headset, speakerphone, etc.) - Hands-free car kit - USB speakerphone/PC speakerphone - Embedded speakerphone for PC/notebook monitor FM1182 features array microphone with beam-forming to suppress non-stationary noise by 20d B. Its superior acoustic echo cancellation performance, up to 60d B, allows a very short distance (4cm) between the placement of the microphone and speaker, even while the speaker delivers 120d B throughput. FM1182 supports dynamic range control, noise suppression for both voice input and output to increase voice intelligibility, and full duplex performance. For Bluetooth applications, the FM1182 provides a serial port interface that supports all formats. Key Features : - Highly integrated single chip solution - Powerful acoustic echo cancellation (60d B AEC) - Extremely low power consumption (35m W) - - - - - - - Requires only single power supply Small form factor Supports 1 & 2 microphone modes Differential inputs/outputs to reduce RF interference and increase noise immunity Dynamic range control to increase voice intelligibility and full duplex UART interface to external controller Serial port interface supports u-Law, A-Law, and linear PCM format Performance: - Adaptive Step-Sized Sub-band process with dedicated Non-Linear Filter delivers 60d B AEC performance - Array microphone with...
