The SiT9104 is the world’s first 3-PLL programmable clock generator with an embedded MEMS resonator. It is designed for consumer and computing applications. The SiT9104 can generate up to three unrelated frequencies with six outputs which allows integration of three oscillators or clock generators into a single chip for more robust and smaller form factor designs.
With its innovative MEMS First™ resonator technology, SiTime is able to mass produce reliable, high performance silicon timing solutions that are ideal for most applications. Like all SiTime products, the SiT9104 3-PLL programmable clock generator is lead free and RoHS compliant.

Key Features and Benefits
- Integration of up to three oscillators for more reliable and smaller form factor designs
- Ultra low jitter
- 5 ps RMS period jitter improves total timing budget margin in high performance designs
- Frequency range of 1 to 220 MHz allows designers to customize the product to their applications, and use the same base product in a variety of different applications
- Tight frequency tolerances of ±25 PPM and ±50 PPM provide designers with a high stability clock for increasing the robustness of their designs
- Ultra fast lead time of 2 to 3 weeks enables fast time to market of end products
- Small form factor, 7.0 x 5.0 x 0.9 mm, saves board space in space-constrained applications by up to 66%
- Programmable operating voltage options of 1.8 V, 2.5 V, or 3.3 V give designers flexibility to use the same chip for different designs
SiT9104 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.
