The gain of the loop integrator is small for high jitter
frequencies, so larger phase differences are needed to make the
loop control voltage big enough to tune the range of the phase
shifter. Large phase errors at high jitter frequencies cannot be
tolerated. In this region, the gain of the integrator determines
the jitter accommodation. Since the gain of the loop integrator
declines linearly with frequency, jitter accommodation is lower
with higher jitter frequency. At the highest frequencies, the loop
gain is very small and little tuning of the phase shifter can be
expected. In this case, jitter accommodation is determined by
the eye opening of the input data, the static phase error, and the
residual loop jitter generation. The jitter accommodation is
roughly 0.5 UI in this region. The corner frequency between the
declining slope and the flat region is the closed-loop bandwidth
of the delay-locked loop, which is roughly 5 MHz for OC-12,
OC-48, and GbE data rates, and 600 kHz for OC-3 data rates.
