SiTime SiT9120 Standard Frequency Differential Oscillator
SiTime SiT9120 Standard Frequency Differential Oscillators cover 31 standard frequencies from 25MHz to 212.5MHz and offer LVPECL and LVDS output signaling types. These oscillators provide industrial and extended commercial temperature ranges, and industry-standard packages: 3.2mm x 2.5mm, 5mm x 3.2mm, and 7mm x 5mm. These package sizes enable drop-in replacement of quartz, SAW, and overtone oscillators without broad changes. SiT9120 oscillators are field programmable, allowing any combination of voltage, frequency stability, and package within the operating range. Specifications include a 0.6ps integrated RMS phase jitter, meeting 1GbE to 10GbE jitter requirements, and ±10ppm, ±20ppm, ±25ppm, and ±50ppm frequency stability options. SiTime SiT9120 Standard Frequency Differential Oscillators span various designs, reducing inventory across system clocking applications in communications, networking, and data centers.
