Abstract :
This paper presents a 50Gbps half rate SerDes transmitter with automatic serializing time window search. By implementing a serializing time window search loop, the serializing timing is guaranteed and circuits running at highest speed such as latches for retiming and clock tree buffers for delay matching are eliminated. Fabricated in 65nm CMOS technology, the transmitter running at 50Gbps consumes only 75mW power under 1.2V power supply. The total jitter of 50Gbps eye diagram is 9.8ps for 1e-12 BER.
