JITTER TRANSFER
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, typically using a voltage-controlled crystal oscillator (VCXO).
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. Table 9
shows the jitter transfer characteristics and/or jitter attenuation specifications for various data rates:
NOTE: The above specifications can be met only with a jitter attenuator that supports E3/DS3/STS-1 rates.
