NOMINAL PERFORMANCE CHARACTERISTICS

FIGURE 3-1:

PL133-47 Additive Phase Jitter: VDD = 3.3V, CLK-100 MHz, Integration Range

12 kHz to 20 MHz, 0.059 ps Typical.

When a buffer is used to pass a signal, 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:
