【Abstract】 An Ethernet receiver for 1.25Gbit/s NRZ data is described. This circuit works at half of the data rate, in order to be adapted with high rate data stream with low power and reduced complexity for design. The main building blocks and operation principles are introduced, and the key parts of the circuit are also described. The circuit adopts 1.8V 0.18祄 CMOS 1P6M technology. Verified with SpectreS simulator, the circuit works properly under different corners. The chip is tested, and the main function is correct.更多还原
