Abstract
The hardware performance of an ISI equalizer and XTC is dependent on the adaptive calibration algorithm used for the XTC combined with the AGC and the DFE. In this paper we describe an automatic calibration algorithm that focuses on high-speed crosstalk cancellation and crosstalk reutilization techniques for single-end I/Os [1]. The crosstalk signal between channels in multiple lanes strongly depends on the channel spacing of the PCB lanes and proximity issues caused by pads and bond wires. Recently developed low-power crosstalk cancellation and crosstalk reutilization schemes are able to achieve high signal integrity even in severe crosstalk environments, where previously, the data eye openings might have been completely closed [1]. The power-efficient adaptive techniques described here are intended for use with the hardware circuits and techniques described in a previous study [1].
