Abstract
The ongoing demand for higher data rates in wireline and optical communications has led to emerging standards in the 100Gb/s+ regime [1]. Although these standards are still in the definition phase they will rely on multi-level signaling such as PAM-4 along with an increasing amount of digital signal processing. In the foreseeable future, a high-performance TX will consist of a CMOS DSP frontend followed by a high sampling rate data converter [2,3], whose design remains a significant challenge. This paper presents a 112Gb/s PAM-4 SST Tx that is based on a quarter-rate 56GS/s 8b SST DAC along with a digital 8-tap FIR filter for channel equalization.
