How are PLLs used in microprocessors?

Zhang H, Yang H G, Wang Y, Liu F, Gao T Q. A 270-MHz to 1.5-GHz CMOS PLL clock generator with reconfigurable multi-functions for FPGA[J]. I have a question regarding the reference clock frequencies that are selectable by the Vivado RFSoC IP block for the ZCU111. The PLL-based Clock Generator provides a cost effective solution for generating various frequencies that are required in today's system and it meets the demand ... Jan 24, 2022 ... In this video we look at what PLLs are used for and how to use them to generate various different clock frequencies for an FPGA design. The power on the default feedback divider is 150 (decimal) with an 8 MHz FRC input clock. The VCO frequency is 1.2 GHz. Page 19. © 2016-2017 Microchip ... Dec 2, 2022 ...
