高精度TCXO
Elite Platform®、Elite X™ 和 Elite RF™ 高精度TCXO是具有卓越动态性能和丰富功能的精密定时解决方案。这些器件解决了电信、射频、网络、边缘同步和精密 GNSS 应用中根深蒂固的定时问题。SiTime 高精度TCXO结合了高稳定性和低相位噪声以及陶瓷 TCXO 的坚固封装，可取代传统的石英OCXO，同时提高可靠性、降低功耗并减小尺寸。
- 严格的稳定性（±0.01 ppm 至 ±2.5 ppm），1 至 220 MHz
- 动态稳定性比石英更好（±0.5 ppb/°C ΔF/ΔT），耐气流和热冲击
- -40°C 至 105°C 的操作独特地实现了无风扇户外设备
- 低相位噪声：10 kHz 时为 -159 dBc/Hz（标称值 19.2 MHz）
- 电池供电的边缘设备功耗更低（110 mW，2.5V）
- I 2 C 数字频率调谐消除了外部 DAC 和对电路板噪声的敏感性
- 片上电源噪声滤波无需专用 LDO
