关于爱普生可编程晶振SG-8002 PLL锁相环电路，晶诺威科技解释如下：

The SG-8002 series contains a PLL circuit and there are a few cases where the jitter value may be increased when this product is connected to another PLL oscillator (cascading connection). We do not recommend this series for analog video clock use and telecommunication synchronization.

爱普生晶体振荡器SG-8002系列为程序烧录晶体振荡器，采用编程PLL锁相技术。若再连接PLL锁相振荡电路，在某些情况下可能增加抖动（jitter）值。不建议该系列用于模拟视频时钟和电信同步应用。

Please check in advance if the SG-8002 series jitter is acceptable to your application.(Jitter specification of the SG-8002 series is max.250 ps/CL=15 pF).

请提前检查SG-8002系列的抖动是否符合您的应用要求。（SG-8002系列的抖动规格为最大250 ps/CL=15 pF）。
