The jitter transfer characteristic is that of second order low-pass filter with the -3dB point at approximately 1MHz-3MHz depending on its internal configuration (also called close loop bandwidth). This means that if the jitter frequency is less than loop bandwidth, it will pass through the PLL and appear on all outputs.
Jitter transfer characteristics of clock buffers actually peaks at 1MHz where the jitter increases and then rolls down with 20-dB/decade attenuation.
