We divide the circuits into two parts: (1) 1: 10 Deserializer. In the deserializer, the serial data (3.125Gb/s) is deserialized into 10-bit parallel data and the comma word is continuously detected. (2) Channel Deskew Circuit. This circuit is to align the data among four channels. After alignment, 32-bit data propagate to the MAC layer via the PCS service interface. In the second part of this report, the simulation result of including an optical filter to reduce the fiber dispersion caused by frequency chirp of a direct modulated laser diode without cooling is presented. With appropriate bandwidth and center frequency, we have demonstrated that the transmission distance can indeed be extended at data rates up to 10Gbps.application/pdf519791 bytesapplication/pdfzh-TW國立臺灣大學電子工程學研究所百億位元乙太網路序列-並列轉換器同步字元偵測通道時脈資料校正電路直接式雷射雷射啁啾光纖色散10G-LX4 EthernetDeserializerComma word detectionChannel deskewDirect modulated laserLaser chirpFiber dispersionreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20021/1/922220E002009.pdf
