High Performance Programmable Oscillators

The SiT8102 is the world’s highest performance programmable oscillator with sub-picosecond phase jitter and ultra low frequency tolerance of ±10 PPM. It is designed for high performance computing, consumer, and networking applications. For example, the SiT8102 supports high speed serial communication protocols such as SATA, SAS, Ethernet, FireWire (1394B), and Fibre Channel.

With its innovative MEMS First™ resonator technology, SiTime is able to mass produce reliable, high performance MEMS oscillators that are ideal for most applications. Like all SiTime products, the SiT8102 high performance programmable oscillator is lead free and RoHS compliant.

Key Features and Benefits

Ultra low jitter

<1 ps RMS phase jitter (random) or 3.5 ps RMS period jitter improves total timing margin in high performance designs

Tight frequency tolerances of ±10 PPM, ±12 PPM, ±15 PPM, ±25 PPM, ±50 PPM, or ±100 PPM provides designers with a high stability clock to increase the robustness of their designs
Ultra fast lead time of 2 to 3 weeks enables fast time to revenue of end products
Small form factor saves board space in space constrained applications
Programmable operating voltage options of 1.8 V, 2.5 V, 2.8 V or 3.3 V provides designers flexibility to use the same chip for different designs

SiT8102 Advantages
All of SiTime’s MEMS-based silicon timing solutions have inherent size, height, robustness, reliability, performance and lead time advantages over the competition. Samples can be delivered in 24-48 hours, and production quantities can be delivered with lead times of 2-3 weeks – the shortest in the industry.
