Abstract

The DP83TC1103x-Q1 PHY is designed to be pin to pin compatible with TJA1103. This document serves as a reference for changing a TJA1103 design to a DP83TC1103x-Q1 design. In many cases, the same board design used for TJA1103 can be used to support DP83TC1103x-Q1. However, it may be necessary to adjust passive components supporting the PHY.
