Min ASIC Node

The 1G Gigabit Ethernet MAC is the most versatile in the Xtremesilica Ethernet portfolio. It supports RGMII, SGMII, GMII, and MII PHY interfaces, making it compatible with the broadest range of external PHY devices and embedded PHY implementations. The core delivers full-duplex 1 Gbps with half-duplex legacy support.

With sub-1 mW idle power, it is ideal for battery-powered IoT devices, automotive ECUs operating in standby, and always-on industrial sensors. The IP is available for every FPGA family and any ASIC node down to 180 nm legacy processes.

Features

Complete GigE Feature Set

Multi-Interface PHY

RGMII v2.0, SGMII, GMII, and MII support in a single synthesizable IP — configure at integration time without re-licensing.

Auto-Negotiation

IEEE 802.3u auto-negotiation for 10/100/1000 Mbps speed selection with MDI/MDI-X crossover detection for plug-and-play operation.

IEEE 1588 PTP

Hardware timestamping for IEEE 1588v2 Precision Time Protocol — sub-100 ns accuracy for industrial control, telecom, and TSN applications.

802.1Q VLAN

Full IEEE 802.1Q VLAN tag insertion, removal, and priority mapping with 802.1p QoS marking for traffic management.

Wake-on-LAN

Magic Packet and ARP offload for Wake-on-LAN while the main processor is in deep sleep, consuming <100 µW standby power.

EEE (802.3az)

Energy-Efficient Ethernet for adaptive low-power link state during idle periods — 50-80% power reduction for IoT and edge deployments.
