Differential Output Programmable Oscillators

The SiTime SiT9102 differential output programmable oscillator is the world’s first to provide ±10 PPM frequency tolerance with sub-picosecond phase jitter. The device is designed for high performance networking, computing, and consumer applications. The SiT9102 supports four programmable differential output signaling levels – LVPECL, LVDS, CML, and HCSL.

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 SiT9102 differential output programmable oscillator is lead free and RoHS compliant.

Key Features and Benefits

Very high frequency stability of ±10 PPM enables designers to solve timing margin issues

Better frequency tolerance allows the system to be more robust against low-frequency environmental noise generated by transformers, fluorescent lights, power lines, etc.
Increased timing margin translates into fewer system errors and higher long-term reliability

Frequency range of 1 to 220 MHz (continuous) and 220 to 800 MHz (selected frequencies) allows designers to customize the product to their applications, and use the same base product in a variety of different applications
Extremely low jitter

<1 ps RMS phase jitter (random) or 2.0 ps RMS period jitter improves total timing budget margin in high performance designs

Ultra fast lead time of 2 to 3 weeks enables fast time to market of end products
Small form factor saves board space in space-constrained applications
Programmable operating voltage options of 1.8 V, 2.5 V, or 3.3 V provide designers with the flexibility to use the same chip for different designs

SiT9102 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.

SiT9102 Applications
