混合信号技术

在混合信号设计中经验至关重要,凭借欧胜代理商超过25年的经验,我们技术精湛和富有经验的设计师与工程师团队能够生产出一些全球最先进的混合信号器件。

欧胜代理商产品开发模式得益于巨大的研发投入,以及成功地预测了客户需求,从而源源不断地向市场提供新的产品:Wolfson建立了一种创造重要的知识产权(IP)流程,这些IP能够不断加强我们的产品组合。我们的设计团队正持续不断地开发更强大、更灵活的产品来满足我们那些引领市场的客户需求。欧胜已经由最初开发分立的混合信号(主要是模拟)器件,演变到开发复杂的、很难被复制的高清(HD)音频系统级芯片(SoC),它包含了尖端的音频模拟IP、数字处理以及声效处理软件算法。

随着全球领先的电子公司都在开发越来越强大和精妙的技术,创新成为了在消费电子行业中取得成功的关键。在所有的消费电子领域中,设计师的压力在于要不断提高的功能集成度和性能,与此同时还要降低产品成本和体积,并延长电池续航时间。

Wolfson代理商已经从向客户销售低价值的大宗器件,转变为与客户合作而为其设计提供高价值的、常常是多组件的高清(HD)音频解决方案,从而影响了其提供给客户的终端产品架构与功能。欧胜的策略是直接与原始设备制造商(OEM)合作,为其终端产品增加价值和带来差异化。无论它们已经是数字消费市场的世界领先者,还是一家具有伟大的、全新的应用理念的新兴企业,欧胜的技术都能够帮助这些OEM实现脱颖而出的设计。
