NR2048 Datasheet | acoustic

High Performance Voice Processor for Mobile Applications Product Data Sheet .acoustic-s. Date: 02/07/2020 Version: 1.0 1. Introduction NR2048 is the new generation of voice processor capable of HD Voice (wideband) and narrow band voice processing, and it is designed to improve intelligibility for voice calls, as well as helping to improve voice recognition mand inputs in noisy environments. It delivers state-of-the-art voice processing capabilities to improve the listening experience of both near-end and far-end users. With acoustics’s proprietary voice processing technology, the NR2048 uses advanced beam-forming technology to track the caller’s voice and filters out the unwanted background noises, providing natural and clear conversations for users in any environment. 1.1 Overview With low power consumption and highly pact footprint, the NR2048 voice processor provides noise suppression, acoustic echo cancellation (AEC) and other adaptive voice enhancements for mobile munications. It also contains specific processing modules to improve voice recognization (VR) rate and improve voice recording in noisy environments. NR2048 provides system integrators and designers great degree of flexibilities to customize each processing module and fine-tune the algorithms to adapt to each device’s unique needs and acoustic path characteristics. This IC can be easily integrated into system architectures with either a split Applications Processor(AP)-CODEC-Baseband or a highly integrated SOC basedband framework. 1.2 Key Features - Highly integrated SOC o High performance voice processor with built-in hardware support for signals from 8KHz to 48KHz sampling rate o Voice processor with on-chip dual-core digital signal processor (DSP) subsystem, which includes hardware putation accelerators, RAM, and ROM o Three indepedent sets of serial port supporting flexible digital data formats, and each can be programmed as PCM, I2S or slave-mode TDM o Five...
