Regarding Table 65 in the LX2160A datasheet, which states: 
 
'PCIe 8G
SDn_PLLm_REF_CLK_P/
SDn_PLLm_REF_CLK_N RMS
reference clock jitter'
 
I understand that when using RMS for jitter, there are two types: period jitter and phase jitter.
 Which characteristic does the above specification refer to?

 periodとphaseの2種類がある認識です。上記はどちらの特性を指しているのでしょうか?
