Webdesign, and f is the offset frequency. As explained in Section V-A, the PLL bandwidth must be drastically reduced when the reference and CP noise is taken into account. In such a case, the PLL can be approximated by a ﬁrst-order system. We represent the input-output transfer function in Fig. 1(a) by φout φin ≈ N 1 + s ω1, (2) WebIn this design, delays and phase shifts are not programmable and they are hardcoded to value 0x10000000017. If required, these bits can also be taken out as an input to design to provide programmability. For dynamic mode, the output clock frequency is calculated based on EQ 1. EQ 1 The output clock frequencies for the clock outputs are:
