  • In pointer adjustment systems, 3 byte SDH clocks are controlled for synchronization. Therefore large jitter is generated in that systems. Bit stuffing technique was introduced as method for reducing pointer adjustment jitter. However, the jitter generated in this systems is also not so small. In this paper, the problems in the bit leaking system are analyzed and new bit stuffing technique is introduced to reduce the jitter sufficiently.

  • Bit leaking technique is analyzed as method for reducing pointer adjustment jitter. The method for jitter reduction is described, and simulation results are represented to illustrate rms jitter performance. The results show that rms jitter value decrease to less than 25% as compared to a conventional pointer adjustment system.

  • Techniques for the reduction of SRTS jitter and pointer adjustment jitter are studied. To reduce the stuffing jitter several methods have been proposed, such as bit leaking, stuff threshold modulation and sigma delta modulation. The characteristics of jitter generated in SRTS and pointer adjustment systen implementing these reduction techniques is analyzed with computer simulation. The results show that ms jitter value decreases to less than 50% as compared to a conventional pointer adjustment system. The amplitude of SRTS jitter using new techniques decreases or Increases dependent on system parameter.
