MEMS Oscillator Offers Breakthrough 70-fs Jitter in Half the Space
SiTime Corporation introduced the SiT9501 differential MEMS oscillator. Based on SiTime’s newly launched third generation MEMS technology, the device delivers uncompromising performance for 100G - 800G optical modules. With the device’s smaller size, customers get up to 50% space savings to integrate more features and reduce development time. The SiT9501 is ideal for other high-performance applications, including datacenter switches, telecom routers, edge servers, AI/graphics cards, and storage controllers.
In anticipation of massive Internet traffic growth, driven by 5G, AI and cloud computing, data centers are increasing throughput. Optical modules and data communications equipment need to deliver faster data rates. Outdoor 5G infrastructure is subject to environmental stressors such as high-temperature, vibration and airflow that can degrade throughput. With the increased data rates and potential environmental stressors, timing margins shrink, requiring lower jitter oscillators to ensure the same quality of service.
In optical modules, a third of the PCB area is consumed by the optical sub-assembly, leaving little room for data processing electronics, and making small size a critical factor in oscillator selection.
SiTime’s new SiT9501 differential oscillator solves both key issues by offering the lowest jitter in the presence of environmental stressors, and the smallest size.
The SiT9501 is the industry’s lowest-jitter programmable oscillator, and includes the following features:
The SiT9501 oscillator is sampling now. Production quantities are planned to be available in Q1 2021. Pricing is provided upon request.
