SiTime推出业界首款车用MEMS片上时钟系统：Chorus汽车MEMS时钟发生器SiTime Introduces Industry's First Automotive MEMS Clock System-on-Chip: Chorus Automotive MEMS Clock Generator
➀ SiTime近日推出了汽车行业首款完全集成的MEMS时钟片上系统（ClkSoC）——Chorus汽车MEMS时钟发生器，该发生器内置故障监测机制，适用于汽车设计的整个时钟生成信号路径。➁ Chorus时钟发生器将MEMS谐振器、振荡器和先进的安全机制集成在一个封装中，与独立的石英振荡器相比，在尺寸减半的同时，性能提升高达10倍，同时提供关键的诊断覆盖范围，以更轻松地实现汽车功能安全标准。➂ Chorus发生器采用SiTime坚固耐用的MEMS计时技术和数据中心同步高精度计时网络，可在-40℃至125℃的温度范围内运行，从而消除安全关键模块设计和定位中的任何热瓶颈。➀ SiTime launched the industry's first fully integrated MEMS Clock System-on-Chip (ClkSoC) for the automotive industry, the Chorus Automotive MEMS Clock Generator, which includes a built-in fault detection mechanism suitable for the entire clock generation signal path in automotive design. ➁ The Chorus clock generator integrates MEMS resonators, oscillators, and advanced safety mechanisms into one package, offering performance improvements up to 10 times greater than quartz oscillators with half the size, while providing critical diagnostic coverage for easier achievement of automotive functional safety standards. ➂ The Chorus generator is designed to meet the timing needs of autonomous driving or advanced driver-assistance systems (ADAS) with its robust MEMS timing technology and high-precision timing networks used in data centers, ensuring reliable operation across a wide temperature range. It also features early fault reporting capabilities to minimize fault tolerance time intervals (FTTI), which are common requirements for automotive safety integrity levels (ASIL).
