Crystal filter bandwidth

Webcomprised of a phase fr equency detector (PFD), loop filter (LF) a nd voltage-controlled oscillator (VCO) as shown in Figure 1. Often the PLL filter is implemented using discrete components. One of the more challenging elements in designing with high-performance PLLs is how to choose the "right" loop bandwidth for a given application. As with WebQuartz crystal filters are the optimum choice where the application requires selective narrow band filtering at HF and VHF frequencies. Because of the extremely high Q of quartz resonators, crystal filters with a fractional bandwidth of the order of 0.01% to 0.5% can be realised with low insertion loss and high selectivity.
