The follow set of curves show the jitter transfer versus frequency with a loop bandwidth value of 60 Hz. The clock
input and output frequencies were both 10.24 MHz. The four curves all use the same data but are graphed at
different scales to illustrate typical gain vs. frequency and peaking. The last curve shows the jitter peaking in detail
that is well below 0.1 dB.
