IEEE 802.1® Clause 4 Tiny MAC
The CT25208 Digital IP core is a standard Clause 4 CSMA/CD MAC exposing a proprietary, FIFO-like MAC Client interface (TX/RX).
Overview
The CT25208 Digital IP core is a standard Clause 4 CSMA/CD MAC exposing a proprietary, FIFO-like MAC Client interface (TX/RX).
On the other end, the CT25208 features a proprietary, MII-like Reconciliation Sublayer (RS) interface, including adapter modules to interface with standard MII/RMII PHYs.
The RTL code is written in plain Verilog 2005 HDL, and it is fully synthesizable on standard cells and FPGA systems.
The flexible MAC Client interface can also be configured for transferring 1, 2, or 4 bytes at a time, supporting both little-endian and big-endian byte order. This feature allows the CT25208 IP to be used with many MCUs and other systems based on shared-memory access by means of a dedicated Bus Adapted interface.
The CT25208 can be used in conjunction with other analog and digital blocks like (a) the CT25205 to implement a digital 10BASE-T1S MACPHY and (b) the CT25203, the CT25205 and the CT25209 to implement a complete OPEN Alliance MACPHY.

Ethernet Auto-Negotiation: Enabling Seamless Link Optimization
Ethernet has evolved significantly from 10 Mbps shared media to today’s multi-hundred gigabit high-speed links. One foundational feature that has enabled this scalability and ease of deployment is Auto-Negotiation (AN).
Enhancing Ethernet Security with MACsec
Ethernet was originally designed for high-speed data transfer and interoperability between devices. However, traditional Ethernet does not provide built-in mechanisms for securing data traffic, such as encryption or authenticity protection. This is where MACsec comes into the picture.
What Makes Ethernet IP Truly Automotive-Grade
This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.
