21.7 A 500mW digitally calibrated AFE in 65nm CMOS for 10Gb/s Serial links over backplane and multimode fiber

Abstract

The demand for bandwidth has fueled the deployment of 10 Gb/s traffic over legacy data links such as serial backplanes (10GBase-KR) and multimode fiber (10 GBase-MMF) which were originally intended for much lower data rates. Under severe channel impairments, a DSP-based transceiver provides robust performance and enables power/area scaling with processes. This work describes a 65 nm CMOS AFE integrated in a DSP-based PHY for 10 Gb/s KR/MMF applications.
