Web1 mrt. 2007 · As discussed in Section 2, the jitter generation is suppressed by boosting loop gain of DLL but the jitter transfer function cannot be improved much by varying loop gain of DLL. In this section we have tried to improve the jitter transfer function of DLL using SAW filter. Finally, the jitter propagation is rejected using Sample/Hold circuit. Web1 dec. 2011 · Abstract. Jitter analysis and a linear model is proposed in this paper which predicts the characteristics of serial-deserial (SerDes) clock and data recovery circuit, and the characteristics include jitter transfer, jitter tolerance and jitter generation are particularly analyzed. The simulation results of the clock data recovery (CDR) model ...

Web6 jul. 2024 · In the second instance, in the figure below, the jitter attenuator’s loop BW is 100 Hz and the output clock is much less jittery. In this particular example, the standard deviation of the jitter attenuated clock’s cycle to cycle jitter dropped from 8.2 ps to 1.1 ps when the loop BW was decreased from 4 kHz to 100 Hz. Conclusion Weba) Jitter transfer: The loop gain of the CDR IC using the PLL technique, on an IC whose jitter transfer specifications meet those of ITU-T Recommendation G.958, must be de- signed to be... http://shanbhag.ece.illinois.edu/publications/ganesh-ICCD2203.pdf mccowan and finch dimsum
