The proposed architecture works at a frequency equal to one-fourth the received data rate and utilizes a quarter-rate early-late type phase detector, a delay line, a delay line controller, and a digitally controlled oscillator (DCO)-based 8-phases generator. The proposed architecture can be adapted easily for different FPGA families, as well as implemented as an integrated circuit. Moreover, it can be used in a deserializer as part of a SERDES in inter-module communication in SoC. The proposed architecture is designed using the Verilog language and synthesized for the Altera DE2-70 development board. Furthermore, the simulation results validate the expected functionality, such as performing quarter-rate phase detection as well as 1-to-4 demultiplexing. The synthesized design requires 117 logic elements using the above Altera board. © 2011 IEEE. date: 2012 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84867955076&doi=10.1109%2fICIAS.2012.6306128&partnerID=40&md5=6146e34b1a4874a7b2f6a4482f976cd4 id_number: 10.1109/ICIAS.2012.6306128 full_text_status: none publication: ICIAS 2012 - 2012 4th International Conference on Intelligent and Advanced Systems: A Conference of World Engineering, Science and Technology Congress (ESTCON) - Conference Proceedings volume: 2 place_of_pub: Kuala Lumpur pagerange: 825-830 refereed: TRUE isbn: 9781457719677 citation: Alser, M.H. and Assaad, M. and Hussin, F.A. and Yohannes, I.
