SIT95147.

Low Jitter, 8-output MEMS Network Synchronizer

这Cascade™SIT95147.is a single-chip MEMS network synchronizer optimized for IEEE 1588 and time synchronization applications. The device comes with 4 independent time domains, 1 mHz to 4 kHz programmable loop bandwidth, low wander mode and fastest hitless switching. Its low noise quad-PLL architecture and programmable output drivers provide up to 8 differential or 20 LVCMOS low jitter clock outputs. It supports 4 additional clock inputs with Frac-N dividers, enabling virtually any input to output frequency translation configurations from 8 kHz to 2.1 GHz.

该网络同步器集成了Sentime的第三代MEMS谐振器。该集成MEMS方法消除了对晶体参考的依赖关系以及所有石英相关问题，提供了一个改善系统鲁棒性的真正时钟系统的芯片：

通过消除晶体电容不匹配，始终准确的时钟合成
即使在寒冷温度和其他恶劣的环境条件下也可以始终可靠启动
由于噪声耦合到晶体接口上没有抖动降级
No activity dips/frequency jumps inherent to quartz
10x更耐振动和板弯曲

这SIT95147.is supported by TimeMaster™ software application to simplify clock tree design. The device can also be shipped with a user-specified, factory pre-programmed default startup configuration. The device configuration can be re-programmed twice using two banks of one-time-programmable (OTP) memory during manufacturing or configured in-system via I2C/SPI for additional BOM flexibility. The SiT95147 is also supported with theSiT6502EBevaluation board.
