SiTime Corporation (NASDAQ: SITM), a market leader in MEMS timing, today 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.
“Over the past 15 years, SiTime has developed and shipped two generations of MEMS resonators that are used in all our oscillator shipments to date. Our third generation MEMS is now ready and delivers up to 7 times better phase noise at half the power,” said Rajesh Vashist, CEO of SiTime. “The SiT9501 is the first of many products to use this technology and continues our tradition of delivering dramatic performance enhancements in every product generation. In space constrained applications such as optical modules, the SiT9501 delivers an unmatched combination of higher performance and smaller size.”
Meeting Tough Requirements of Data Communications and Optical Modules
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.
Features of the SiT9501 Differential MEMS Oscillator
The SiT9501 is the industry’s lowest-jitter programmable oscillator, and includes the following features:
- Popular networking frequencies from 25 MHz to 644.53125 MHz
- 70 femtoseconds of RMS phase jitter
- 2.0 x 1.6 mm package, the industry’s smallest. Also available in other industry standard packages.
- Wide temperature range, from -40 to +105°C
- On-chip voltage regulators to filter power-supply noise, enhancing power integrity for module designs
- Innovative FlexSwing™ driver reduces power consumption by 30% and integrates source-bias LVPECL resistors
