WebSep 30, 2016 · Referring now to FIGS. 2-4, FIG. 2 shows an efficient and simple frequency divider system 200 using a direct fractional frequency divider (DFFD) approach. A high frequency crystal clock source 202, for example 2.5-5.0 GHz, provides a clock signal CLK to an input 204 of a PLL 206. WebThe digital clock divider includes high speed 3/4 dual modulus prescalar, a 24 modulus divider controller and 3 stage Delta-Sigma Modulator. The divider works up to 3.24GHz. The total power consumption is from 4mW to 9mW based on the different working modes. A MASH111 architecture is selected to implement the fraction-N divider. 1. Introduction
