So, to get to let's say 100-times the cutoff freq (with an adiitional divide by 8 ) the PLL would run at about 2 MHz. So all integration advantages of pure digital chips are preserved, there is no design effort for a new chip generation and the PLL also can be used in a FPGA. The problem is the electronic model should be available in his simulation environment and be fast in simulation. Selection of components to set the lock field and the capture field.

Topics include VCOs, loop filters, phase detectors, time-to-digital converters, VCO-based analog-to-digital converters. Metal outline. The IC has 0. On some 4046 data sheets, the plots that show the center frequency as a function of the frequency-setting components, are hard to read. Due to the relatively slower bus clocks compared to the processor, it is necessary to use phase-locked loops (PLL’s) for frequency multiplication and phase alignment of the clocks. Figure 26-32: Circuit Schematic of Phase Detector In this paper, a first ever exact and nonlinear model based on the phase equations of the second order voltage switched charge pump phase locked loop (VSCP-PLL) is established by using an event driven (ED) technique.
