IEEE 802.3cg® 10BASE-T1S Analog Front-End

Overview

The CT25203 implements the analog front end of an IEEE 802.3cg® 10BASE-T1S physical layer.

It can be used in conjunction to other analog and digital blocks like (a) the CT25205 to implement a complete physical layer ethernet device, (b) the CT25207 to implement a complete OPEN Alliance PMD Interface and (c) the CT25209, the CT25208 and the CT25205 to implement a complete OPEN Alliance MACPHY.

The CT25203 has been designed in GlobalFoundries 130n-BCD process but also successfully and timely ported in other BCD silicon process technologies.
Availability of a complete IEEE physical layer Test Chip vehicle (CT25205_TC) and Evaluation Boards.

The BCD process is required to meet all EMI directives to be used in the Automotive and Industrial environments.
