9.7.4 Jitter Transfer
Jitter transfer or jitter attenuation refers to the magnitude of jitter at the output of a device for a given amount of jitter
at the input of the device. Input jitter is applied at various amplitudes and frequencies, and output jitter is measured
with various filters depending on the applicable standards.
Since intrinsic jitter is always present, jitter attenuation will appear to be lower for small input jitter signals than
larger ones. Consequently, accurate jitter transfer function measurements are usually made with large input jitter
signals (e.g., 75% of the specified maximum jitter tolerance).
The internal DPLL is a first order type 2 component, so a frequency offset doesn’t result in a phase offset. Stratum
3 requires a -3 dB frequency of less than 3 Hz. The nature of the filter results in some peaking, resulting in a -3 dB
frequency of 1.9 Hz and a 0.08 dB peak with a system clock frequency of 100 MHz assuming a p_shift value of 2.
The transfer function is illustrated in Figure 24 and in more detail in Figure 25. Increasing the p_shift value
increases the speed the DPLL will lock to the required frequency and reduces the peak, but also reduces the
tolerance to jitter - so the p_shift value must be programmed correctly to meet Stratum 3 or Stratum 4/4E jitter
transfer characteristics. This is done automatically in the API.
9.8 Maximum Time Interval Error (MTIE)
In order to meet several standards requirements, the phase shift of the DPLL output must be controlled. A potential
phase shift occurs every time the DPLL is re-arranged by changing reference source signal, or the mode. In order
to meet the requirements of Stratum 3, the DPLL will shift phase by no more than 20 ns per re-arrangement.
Additionally the speed at which the change occurs is also critical. A large step change in output frequency is
undesirable. The rate of change is programmable using the skew register, up to a maximum of 15.4 ns / 125 μs
(124 ppm).
