200GE / 400GE Ethernet MAC Cores

The Precise-ITC 200G/400G Ethernet IP cores are cutting edge solution to the 200G/400G Ethernet application.  It supports the MAC layer function based on the IEEE 802.3bs-2017.

There are 3 MAC Cores : 200G MAC, 400G MAC or 200G/400G MAC. Comprehensive MAC/RS statistics are supported in all MAC Cores.  TX or RX MAC statistics can be optionally “removed” to save logic area. All MAC cores are designed with low latency and cut-through features.

This core is suitable for use in switch or interface cards or any application that requires a MAC for 200G/400GbE. For a complete Ethernet solution, the MAC Core seamlessly integrates with the Precise-ITC 200G/400G PCS cores.
