Web22 okt. 2024 · Specifying a PLL Part 2: Jitter Basics. By Julian Jenkins, Perceptia Devices. 1. Introduction. No real clock sources (PLL’s, DLL’s, Crystal Oscillators, even function generators) exist that have a single, fixed value for their output period. The output period of all real clock sources changes over time. Web3.6 jitter transfer function: Ratio of the output jitter to the applied input jitter as a function of frequency. 3.7 output jitter: Jitter at the output of equipment that is embedded in a …

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. WebTypically, the loop transfer function is derived as a function of the output voltage. If in D-CAP™ mode, the output voltage is directly compared by the PWM comparator. Theoretically, the gain and the bandwidth of a comparator are infinite. As a result, the loop gain from the output node becomes infinite. This means
WebThe jitter transfer is given by (1) In cases where the loop filter consists of only a capacitor (), the jitter transfer contains a single pole ( ) and exhibits no jitter peaking. For the …
