1 Introduction

While the Maxlinear XR34350 and SP339E/B multiprotocol transceivers have many similarities to TI’s THVD4431, the THVD4431 multiprotocol transceiver offers several advanced features and more integration that enable diverse applications and improved system performance. This system rollover document outlines how to replace the Maxlinear XR34350 and SP339E/B multiprotocol transceivers with TI’s THVD4431 by comparing the differences in feature set and pinout.
