SiTime MEMS VCXOs提供特殊的动态性能ormance and the highest reliability for video distribution (CMTS), networking, telecom, and instrumentation applications. These devices are engineered to maintain the same phase noise and frequency tuning accuracies in the presence of common environmental hazards, such as shock, vibration, noisy power supply, and EMI. They enable equipment, such as cable headend and remote radio head (RRH), to deliver the highest performance, best reliability, and the highest quality of service in uncontrolled environments, such as un-airconditioned basements or rooftops.

• 在1 Hz步骤中从1 MHz到725 MHz的任何频率
• ±15 ppm，整个温度范围内的最佳动态稳定性（-40至+ 85°C）
• 0.02 PS / MV电源噪声抑制（PSNR），降低电源要求
• Best (0.1%) and widest (±25 to ±3200 ppm) pull range linearity, 50x better than quartz

sit's Elite Platform™ I2C/SPI oscillators enable users to program output frequency and pull frequency in-system using a digital interface, offering designers great flexibility. This family offers ultra-low jitter and utilizes SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technology to deliver exceptional dynamic performance.

• Ideal for replacing multiple timing components in systems that support multiple frequencies such as telecom, networking, server, storage, broadcasting, test and measurement equipment
• Any-frequency mode for programming output frequency via I2C or SPI from 1 MHz to 725 MHz
