Functional Specifications

• 1.6T Ethernet UMAC IP is optimized for ultra-low latency, ensuring real-time communication in critical applications such as AI and HPC.
• Configurable thresholds to optimize transmission delays and fine-tune performance for specific application needs.
• 1024-bit packed TDM interface, supporting a 16x66b 64b/66b PCS-encoded interface.
• The 1.6T UMAC supports jumbo frames up to 16KB, which is ideal for large data packets commonly used in high-performance computing (HPC) and cloud services.
• Dynamic mode switching allows channels to change modes without interrupting or interfering with other channels.
