南方軸承(002553.SZ):採用22nm先進製程的新一代TWS智能藍牙語音SoC芯片預計將於2022年量產
格隆匯12月8日丨南方軸承(002553.SZ)公佈,近日,公司控股子公司上海圳呈微電子技術有限公司(“上海圳呈”)研發的採用22nm先進製程的新一代TWS智能藍牙語音SoC芯片已經完成流片、封裝和主要測試工作,核心指標測試結果均符合預期設計要求,預計將於2022年量產。
該款芯片的性能特點: (1)上海圳呈此次研發的新一代TWS智能藍牙語音SoC芯片,採用22nm先進制程,在國內處於領先水平,具有更高的集成度,該芯片內部集成Cadence HiFi系列高性能DSP處理器、高性能語音降噪處理模塊、低功耗雙模藍牙射頻模塊、24-bit 高保真Audio CODEC,除應用於TWS耳機外,還可作為主控芯片應用於其它智能音頻設備。
(2)該芯片集成自主研發的核心算法,上海圳呈擁有完全自主知識產權,得益於該算法,在智能語音降噪、AI交互、個性化和健康體驗方面,該芯片具備獨特的性能優勢。
(3)該芯片集成自研的 Spatial Audio(空間音頻)技術和算法,直接在TWS智能藍牙耳機端實現3D音效。
(4)該芯片內含自研定製的高效率PMU(電源管理模塊),能降低芯片功耗,同時有助於設備在實現安全快速充電的同時可以有效提升整體續航時間15%以上。
上海圳呈自成立以來,在技術研發和產品量產轉化上不斷取得突破,累計設計流片成功近20款芯片,其中過去五年一共做了8款先進工藝SoC芯片,每一款都實現量產。22nm新一代TWS智能藍牙語音SoC芯片的成功研發進一步豐富了上海圳呈核心技術儲備,有利於增強其核心競爭力。
公司於2020年11月通過增資方式控股上海圳呈,該款芯片的成功研發,也有利於鞏固公司在相關領域的市場競爭力與市場佔有率,將對公司長期發展戰略的實施具有推動意義。
