Abstract

A jitter suppression apparatus in a data transmission system includes a phase detector circuit to determine a plurality of phase errors between sync pulses of a data line and sync pulses of a reference line, and an adapted phase error offset circuit, coupled to the phase detector circuit, to generate a plurality of phase error offsets and adaptively offset the plurality of phase error offsets. The jitter suppression apparatus may also include a stuff/delete slicer, coupled to the adapted phase error offset circuit, to generate a plurality of stuff/delete signals such that a framer can determine what type of data frames to send to a communication channel of the data transmission system. A jitter suppression method includes steps of detecting a phase error, computing a phase error offset, and filtering out the phase error offset. An integrator may be used to filter out the phase error offset input to the stuff/delete slicer.
