6.1.2. Reference Jitter
Jitter on the reference input has a roughly one-to-one transfer function to the output jitter over the bandwidth
ranging from 100 Hz up to 30 kHz. If a crystal is used on the XA/XB pins, the reference will have low jitter if a
suitable crystal is in use. If the XA/XB pins are connected to an external reference oscillator, the jitter of the
external reference oscillator may contribute significantly to the output jitter.
A typical reference input-to-output jitter transfer function is shown in Figure 20.
