2 kHz - 20 MHz, 0.059 ps Typical.

When a buffer is used to pass a signal then the buffer will add a little bit of its own noise. The phase noise on the output

of the buffer will be a little bit more than the phase noise in the input signal. The noise added by the buffer to the input

signal is quantified by the additive phase jitter defined by the following formula:
