Design and implementation of CDR and SerDes for high speed optical communication networks using FPGA

In this paper, we design and implement the Clock and Data-Recovery (CDR) with Serializer/Deserializer (SerDes) on Spartan SP605 supports a data-rate up-to 3.2 Gbps with locking time less-than 5×10<sup>-7</sup> s, and bit-error rate less-than 10<sup>-10</sup>.
