overview DO 254 IP



The MTIP_MAC1G module provides, with a single IP Core, a solution for Ethernet applications operating at 10/100 or 1Gbit. It allows a SoC to be connected to an external Ethernet Network. The hardware item only covers digital layers of the IEEE 802.3 MAC bus architecture. It supports transparent (for switching application) and full Ethernet frame handling for connected device.

With its unique internal architecture the digital core is optimized for low gate count and low latency applications. For efficient power management, the core can implement the Magic Packets detection.
The MTIP_MAC1G is able to recover from SEU (self healing feature) and to report any detected errors with the help of its embedded reliability features. Detected errors are then reported to external system and to internal sub-system.
The MTIP_MAC1G matches major needs of any critical application and mainly those which require a DO-254 DAL-A compliance in aerospace area.

The development has been done according to the RTCA/DO-254 ED-80 guidelines.

This component has been developed, verified and licensed by SILKAN.
