University of Maine
Devon Fernandez and Sanjeev Manandhar
Contains two Digital Phase Locked Loops. One has an operating frequency of 400MHz generated by a vco based on differential logic, a fixed frequency divider of 64, and an xor phase detector. The other has an operating frequency of 25MHz, a programmable frequency divider, and a phase frequency detector.
