Modem (cable/DSL/GFAST)

Block diagram

Overview

Our integrated circuits and reference designs help you create broadband modem systems that enable support for the latest standards like G.mgfast and DOCSIS 3.1. Our high-speed line drivers support 106-MHz and 212-MHz G.fast digital subscriber line (DSL) profiles that use native discrete multitone modulation (DMT) signals.

Design requirements

Modern modem (cable/DSL/GFAST) systems require:

  • Ability to overcome and accommodate wide variations of signal conditions.
  • Superior external machine interface (EMI) and distortion performance with low-power consumption.
