Low Jitter, 10-output MEMS Clock Generator
The Cascade™ SiT95141 is a single-chip MEMS clock generator optimized for the highest level of clock tree integration. This clock-system-on-a-chip (ClkSoC) consolidates multiple clock ICs and oscillators into a single device. Its low noise quad-PLL architecture and programmable output drivers provide up to 10 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.
This clock generator integrates SiTime’s third-generation MEMS resonator. This integrated MEMS approach eliminates the traditional clock dependency on crystal reference and quartz related issues, and improves system robustness:
- Always accurate clock synthesis by eliminating crystal capacitive mismatch
- 即使在寒冷的温度和其他恶劣的环境条件下,始终可靠启动
- 由于噪声耦合到晶体界面上没有抖动降级
- 无活动倾斜/频率跳跃与Quartz固有
- 10x更耐振动和板弯曲
The SiT95141 is supported by TimeMaster™ software that simplifies 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.SIT95141也得到支持亚博电竞SiT6503EBevaluation board.
