The SiT9103 is the world’s first 3-PLL differential output programmable clock generator with an embedded MEMS resonator and sub-picosecond RMS phase jitter. It is designed for high performance networking, computing, and consumer applications. The SiT9103 can generate up to three unrelated frequencies which allows integration of three oscillators into a single chip enabling more robust and smaller form factor designs. This device also 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 silicon timing solutions that are ideal for most applications. Like all SiTime products, the SiT9103 3-PLL differential output 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
• 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
• Ultra low jitter
• <1 ps RMS phase jitter (random) or 5.0 ps RMS period jitter improves total timing margin in high performance designs
• Tight frequency tolerances of ±25 PPM and ±50 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 market of end products
• Small form factor, 7.0 x 5.0 x 0.9 mm (L x W x H), 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 gives designers flexibility to use the same chip for different designs
