11.3Gb/s CMOS SONET-compliant transceiver for both RZ and NRZ applications

An 11.3Gb/s CMOS SONET-compliant transceiver is designed to work in both RZ and NRZ data formats. The TX driver exhibits 17ps rise/fall times, 0.25ps
_rms
RJ, and 2ps
_pp
DJ. The RX has a multi-stage vertical threshold adjustment circuit. It achieves 5mV
_pp-diff
RX input sensitivity with 0.54UI jitter tolerance. The transceiver core area occupies 1.36mm
²
in 65nm CMOS and consumes 214mW.
