Jitter Transfer function is defined as the ratio of jitter on the output relative to the jitter applied on the input
versus frequency. There are two distinct characteristics in jitter transfer, jitter gain (jitter peaking) defined as
the highest ratio above 0dB and jitter transfer bandwidth. The overall jitter transfer bandwidth is controlled by a
low bandwidth loop.
The jitter transfer function is a ratio between the jitter output and jitter input for a component, or system often
expressed in dB. A negative dB jitter transfer indicates the element removed jitter. A positive dB jitter transfer
indicates the element added jitter. A zero dB jitter transfer indicates the element had no effect on jitter.
The jitter attenuator within the XRT91L31 meets the latest jitter attenuation specifications and/or jitter transfer
characteristics as shown in the Figure 26.
