    NXH3675已通过蓝牙®5.3低功耗(LE)音频标准认证,可实现具有超低功耗和超低延迟的高质量、多流无线音频流
    NXP Semiconductors N.V. (Nasdaq stock code: NXPI) has announced the launch of a high-quality audio streaming solution, NXH3675, which is a highly integrated single-chip 2.4 GHz transceiver certified to the Bluetooth 5.3 LE Audio standard. Developers can develop innovative Bluetooth audio products with high-quality audio transmission, broadcasting capabilities, and multiple audio streams and data channels based on this solution. By using NXP‘s optimized audio streaming protocol, this device can provide ultra-low power consumption and achieve ultra-low latency for advanced use cases. The target applications of the solution include game headphones, hearing aids, speakers, and TV transmitters, as well as wireless headphones, earplugs, speakers, and microphones.
Product Importance
    The release of Bluetooth LE Audio marks the entry of a new era in Bluetooth audio technology, with more exciting new features about to be unlocked, bringing users a better experience. Bluetooth audio device consumers have reached millions, and headphones, hearing aids, and other listening devices have been integrated into people‘s daily lives. Recent market reports show that the shipment volume of Bluetooth audio streaming devices is approximately 1.3 billion units in 2021, and it is expected to reach 1.5 billion units by 2023. In these applications, the Bluetooth LE Audio standard not only improves audio quality to a higher level, but also brings a new way of audio experience. The new standard supports audio sharing, auditory assistance, and more new use cases that traditional Bluetooth audio cannot achieve. Enzip has always led the development of Bluetooth audio technology and is currently one of the key participants in the new generation Bluetooth 5.3 LE Audio standard.
    Karolien De Baere, Product Marketing and Business Development Department of NXH3675, stated, "The new Bluetooth LE Audio standard will bring a brand new wireless auditory experience. This requires wireless transceivers to have advanced audio processing capabilities, namely high energy efficiency and low latency. The NXH3675 fully complies with the new generation Bluetooth LE Audio standard, supporting multiple signal streams, while also possessing excellent low power consumption and ultra-low latency characteristics
