Overview

The CT25207, in combination with the CT25203, implements a complete OPEN Alliance TC14 10BASE-T1S PMD Interface. The IP’s tasks are:

  • perform the boot sequence and drive the platform outside the IP to do the proper startup sequence after POR and after WAKE request
  • recognize the encoded TX commands and keep updated the state of the PMD FSM after boot
  • drive the platform outside the IP to do the shutdown sequence to enter LOWPOWER mode
  • Filter ED and RX to fulfill the requirements of OPEN Alliance TC14 10BASE-T1S PMD I/F
  • detect collisions on the line when transmitting and signal them on ED pin
  • generate TX pulses for Topology Discovery with proper PRBS sequence
  • perform WUT validation for wake-up

The IP also includes a MDIO slave that allows access to Clause 22 PMD standard registers and to IP specific registers (both embedded in the IP) and to custom registers (to be placed outside the IP).

Three Ethernet Design Challenges in Industrial Automation

As factories, process plants, and robotics platforms become increasingly intelligent and interconnected, the demand for stable, low-latency data links has pushed Ethernet deeper into embedded systems. However, since designing Ethernet connectivity into industrial chips comes with its technical and logistical hurdles, engineers may face challenges when implementing Ethernet in industrial designs.

Powering Scale Up and Scale Out with 224G SerDes for UALink and Ultra Ethernet

At the recent ECOC 2025 conference in Copenhagen, Cadence showcased its key role in enabling the future of AI infrastructure with live silicon demonstrations of several essential IP technologies for emerging 800G and 1.6T networks. Powered by Cadence's 224G SerDes IP, Cadence's Ultra Accelerator Link (UALink 1.0) scale-up and Ultra Ethernet scale-out networking solutions deliver the performance, flexibility, and interoperability needed for next-generation AI factories and hyperscale data centers.

Ultra Ethernet Security: Protecting AI/HPC at Scale

As artificial intelligence and high-performance computing (AI/HPC) reshape industries, the need for robust, scalable, and secure connectivity has never been greater. Built from tightly integrated CPUs, GPUs, and SmartNICs, today’s compute clusters demand high-throughput, low-latency networks that can scale from die-to-die to multi-rack deployments.
