According to reports, this breakthrough solution is designed for in-vehicle audio transmission applications, and is jointly developed by SRP and the world's leading car manufacturers, aiming to strengthen the supply chain security in this field, and strive to become a highly competitive audio transmission solution in the market with excellent product performance.

In the field of in-vehicle applications, ASN not only realizes the two-way data transmission between the host and the external power amplifier in the car, but also realizes the interconnection between the digital signal processor (DSP) and the sensor network such as microphones and accelerometers, providing advanced transmission solutions for in-vehicle microphone pickup, active noise reduction and road noise reduction. In the application of conference system, ASN can expand the playback capability of microphone array nodes or active speaker networks to ensure that the pickup and amplification in the conference are clearly distinguishable, and improve the efficiency and quality of the conference.

ASN automotive chips are divided into two versions, TPDA1000Q and TPDA1001Q, of which TPDA1000Q is a fully functional version, and TPDA1001Q is specially designed for automotive microphone modules. Both versions are also subject to strict AECQ100 automotive approvals and have a temperature range of -40°C to +105°C.

In terms of product performance and advantages, according to SRP, ASN is a high-reliability long-distance vehicle lossless audio bus chip, which is used in intelligent cockpit audio systems to solve many challenges with point-to-point analog connection characteristics, including cable weight, cable cost, wiring problems and reliability of multiple connections, and can realize advanced audio and acoustic applications in the automotive field, including audio ECU, active noise reduction, road noise reduction, audio partitioning, emergency call eCall, etc., to achieve echo cancellation, Cooperate with microphone and power amplifier for ANC active noise cancellation and other functions; Reduce system and cable cost, weight, complexity, etc., by using fewer cables, which in turn reduces vehicle weight and increases range.

At present, SRP ASN products have been verified by many OEMs and Tier1s, and have been recognized by customers for their excellent performance, and ASN products will be available in bulk from December 2024. In the future, SRP will be committed to continuous innovation and research and development, further expand the product layout of audio transmission, and provide ASN products with larger bandwidth to meet customers' urgent needs for more audio channel transmission, and provide customers and the market with more abundant and efficient audio solutions. At the same time, SRP will continue to strengthen technical barriers, enrich the product matrix, and help the new development of automotive electronics technology with innovative technical capabilities to drive a better future for automobiles.
