The PLL have been developed as phase locked loops in a variety of applications. This PLL generates 60~300MHz clock referenced at 8~20MHz. The output clock frequency is selected by the resister M, N
“FOUT = FIN/M*N”
This 100MHz&125MHz PLL allows implementation of integer-N frequency synthesizers when used with an internal loop filter and external reference frequency.
It is designed in 130nm BCDMOS technology for automotive applications and consists of phase and frequency detector(PFD), charge pump(CP), analog loop filter, voltage..
For digital signal processing, frequency synthesizer is required to generate desired clock. A frequency synthesizer is an electronic circuit to generate some range of frequency. Frequency synthesizer is used in many case of digital circuit scheme. For example, DVFS that controls the frequency of the system clock to inc..
