Parameter
PHASE NOISE AND SPURIOUS
This value is incremental. That is, it is in addition to the jitter of the LVDS or CMOS output without the delay. To estimate the total jitter, the LVDS or CMOS output jitter
should be added to this value using the root sum of the squares (RSS) method.
CLK1 = 400 MHz
