A Study on the DPLL Implementation using the WDM Phase Detector

WDM 방식을 이용한 DPLL 구현에 관한 연구

A wave difference method(WDH) phase detector for timing recovery is designed in the digital subscriber loop receiver. This paper describes the architecture and experimental results of the WDM, tankless timing extraction PLL. The results show that the designed WDM timing extraction circuit have stable jitter performance without the use of high precision LC tank circuit.
