224G PHY IP for AI Networks: Extending DAC Reach and Reliability for Next-Gen Data Centers

As the demand for AI/ML training and hyperscale cloud workloads surges, achieving reliable data transmission at 224 Gbps presents unique challenges. This white paper delves into the architectural innovations that enable passive Direct-Attach Copper (DAC) cables to maintain performance over extended distances, addressing critical issues such as:

• Signal Integrity: Strategies to mitigate frequency-dependent loss and inter-symbol interference.
• Crosstalk Management: Techniques to reduce interference and enhance signal clarity.
• Power Efficiency: Balancing performance with lower power consumption for sustainable operations.
• Extended Reach: Enabling reliable operation over 2 meters and beyond, surpassing traditional limitations.
