SANTA CLARA, Calif.--(BUSINESS WIRE)--Aug. 4, 2020-- sitCorporation（纳斯达克：SITM）是MEMS时序的市场领导者，今天宣布了Cascade™系列MEMS时钟IC，用于5G，有线电信和数据中心基础设施。这种时钟系统的芯片（CLKSoC™）系列，SIT9514X包括betway手机客户端,jitter cleaners， 和网络同步器that deliver multiple clock signals in a system. This clock family uses SiTime’s recently launched third-generation MEMS resonators that deliver higher performance with lower power.

Communications and enterprise electronics have previously used clock ICs with external quartz references to integrate multiple timing functions and to distribute clock signals. SiTime’s new, all-silicon clock architecture provides more integration by integrating a MEMS resonator reference inside the package. More importantly, with SiTime’s proven MEMS technology, the Cascade clock-system-on-a-chip delivers up to 10 times higher reliability and resilience, enabling the 5G vision of zero downtime. Either standalone or together with SiTime’s MEMS TCXOs and OCXOs, the SiT9514x delivers a complete timing solution for applications such as 5G RRUs, small cells, edge computers, switches, and routers.

由于许多原因，“Sentime继续扩大我们对通信企业市场的重点。我们的MEMS技术非常适合解决新兴5G基础设施的艰难时机挑战。这代表了多年来生产使用的环境的大型增长机会，“ Rajesh Vashist境内首席执行官。“今天，我们的Elite Platform™Super-TCXOS™和Emerald™Ocxos在该市场上有多种设计。我们正在通过引入级联家庭扩展我们的强大立足点。这是我们时机业务的自然下一步，但它也让我们更接近客户，因为我们共同努力定义他们的时钟树。事实上，级联设备提供了一个完整的时钟系统，可让我们的客户简化其设计并将时间缩短到市场。作为MEMS谐振器，振荡器和时钟IC的唯一提供者betway开户官网，以及为客户提供系统级优势，Sentime继续转换 80亿美元timing market.”

5G is expected to deliver 10 times faster speeds and 10,000 times more data, with 50 times lower latency and zero downtime. To make this vision a reality, 10 to 30 times more devices will be deployed, many of them in uncontrolled environments close to the consumer. Each of these connectivity gains is dependent on the accuracy, resilience and reliability of the timing heartbeat of the system. Silicon MEMS timing technology inherently provides better reliability and resilience which is critical to support the quality of service planned for 5G.

景型完整的时钟系统的芯片的好处

• Integrated MEMS resonator eliminates issues with quartz such as capacitive mismatch, activity dips, susceptibility to shock, vibration, and EMI
• Four independent PLLs, with maximum flexibility to support time synchronization applications where multiple independent clock domains are required
• Up to 11 outputs with an operating frequency range of 8 kHz to 2.1 GHz, as well as a 1 PPS (pulse per second) output, for maximum frequency agility
• Programmable PLL loop bandwidth down to 1 milli-Hz for maximum filtering of wander or network noise in IEEE 1588 and synchronous Ethernet
• Fail-safe operation in case of input clock failures through faster hitless switching between four independent inputs. In such a situation, the device automatically switches to different input clock sources with minimum phase transient at the output, allowing the downstream PLL to remain locked, and the system to continue to operate reliably
• Excellent PSNR for highest performance in the presence of power supply noise
• 最小的外部滤波电路，用于更简单的设计，空间节省和BOM减少
• Rich programmable features and configuration options: (1) Blank ISP (in-system programmable) devices provide maximum flexibility; (2) Pre-programmed devices enable system boot up without software configuration for maximum simplicity
• EVBs and TimeMaster™ software enable users to map clock configurations and generate the scripts for software integration, which speeds development
