供应SITIME 温补晶振TCXO 方波输出SIT5156 音频与视频MEMS振荡器

SiTime的MEMS高精度振荡器经过精心设计，能在气流、快速温度变化、冲击、震动、供电不足及EMI等恶劣环境影响下提供业界最稳定的时钟解决方案。上述器件可根据频率、精度、电压和拉动范围之间的任意组合在工厂中进行编程，从而不仅无需等待漫长的交货周期而且还能消除与石英TCXO和OCXO相关的定制成本。

Super-TCXOsElite Platform™ Super-TCXO是精度非常高（±0.1ppm到±2.5ppm）且频率为1到220MHz不等的高精度振荡器，具有无与伦比的动态性能和丰富特性。上述器件能让根深蒂固的时钟问题迎刃而解，充分满足电信、网络和高精度GNSS系统的需求。其也能用来在新兴的5G和IEEE 1588同步应用中替代传统的石英OCXO，同时降低功耗并减小尺寸。动态精度提升30倍（约为1ppb/°C的ΔF/ΔT），抗气流和热冲击-40 °C到105 °C的工作温度范围理想适用于无风扇的户外设备I2C数字频率调谐功能，无需外部DAC，同时减小对电路板噪声的敏感度片上电源噪声过滤，无需专用的LDO无主动突降或微跳问题。

The SiT5156 Super-TCXO™ is a highly flexible, tight-stability oscillator for high-reliability systems in industrial, server and storage, networking and telecom. Based on SiTime’s unique DualMEMS™ temperature sensing and TurboCompensation™ technology, this device delivers excellent dynamic performance in the presence of common environmental hazards, such as airflow, temperature perturbation, vibration, shock, power supply noise, and electromagnetic interference (EMI).

The SiT5156 can be factory-programmed to any combination of frequency, stability, voltage, and pull range. This programmability enables designers to customize MEMS TCXO configuration for best system performance while eliminating the long lead time and customization costs associated with quartz devices.
