Overview
The 10/100/1000Mbps Tri-mode Ethernet MAC offers an IEEE802.3-2015 compliant solution that meets the requirements for tri-mode LAN in NIC (Network Interface Card) applications.
Tthe 10/100/1000Mbps MAC IP includes:
* AXI4-Streaming or Avalon-Streaming, FIFO based user side interface
* Triple speed MAC with MII/GMII PCS side interface and a simple FIFO based user side interface
* GMII to RGMII interface wrapper
* Statistics counter block (for RMON and MIB)
* MDIO cores for external PHY status/control

Key features
- Implements the full 802.3 specification with preamble / SFD generation, frame padding generation, CRC generation and checking on transmit and receive respectively.
- Dynamically configurable to support 10Mbps, 100Mbps or 1000Mbps operation
- Support for 10/100Mbps full duplex or half duplex operation and 1000Mbps full duplex mode selectable via a Core configuration option
- Seamless interface to commercial Ethernet PHY device via an 8-Bit GMII or 4-Bit RGMII interface operating at 125MHz for GiGE mode and via a 4-Bit MII interface operating at 25/2.5MHz for 100/10Mbps modes
- When operating in Full Duplex mode, implements fully automated XON and XOFF Pause Frame (802.3 Annex 31A) generation and termination providing flow control without user application intervention
- Pause frame generation additionally controllable by user application for traffic flow control
- In half-duplex mode, provides full collision support, including jamming, back-off, and automatic retransmission
- Support for VLAN tagged frames according to IEEE 802.1Q.
- Support any type of Ethernet Frames such as SNAP/LLC, Ethernet-II/DIX and VLAN tagged frames.
- Programmable MAC address filtering; discards frames with mismatching destination address on receive (Except Broadcast and frames)
- Programmable Promiscuous mode support to omit MAC destination address checking on receive Multicast address filtering on receive based on 64 entries hash table reducing higher layer processing load
- Optional multi-cast address filtering with 64-bit HASH Filtering table providing imperfect filtering to reduce load on higher layers
- Programmable frame maximum length providing support for any standard or proprietary frame length (e.g. 9K-Bytes Jumbo Frames)
- Status word available with each Frame on the user interface providing information such as frame length, VLAN frame type indication and error information
- Optional padding termination on RX path for NIC applications or forwarding of unmodified data to the user interface
- Internal GMII/MII Loop-back Statistics indicators for frame traffic as well as errors (alignment, CRC, length) and pause frames
- Simple handshake user application FIFO interface with programmable threshold levels ensuring data rates of 1Gbps with full back-to-back frame transfer support
- Implements statistics and event signals providing support for 802.3 basic and mandatory managed objects as well as IETF Management Information Database (MIB) package (RFC 2665) and Remote Network Monitoring (RMON) required in SNMP environments.

Ethernet Auto-Negotiation: Enabling Seamless Link Optimization
Ethernet has evolved significantly from 10 Mbps shared media to today’s multi-hundred gigabit high-speed links. One foundational feature that has enabled this scalability and ease of deployment is Auto-Negotiation (AN).
Enhancing Ethernet Security with MACsec
Ethernet was originally designed for high-speed data transfer and interoperability between devices. However, traditional Ethernet does not provide built-in mechanisms for securing data traffic, such as encryption or authenticity protection. This is where MACsec comes into the picture.
What Makes Ethernet IP Truly Automotive-Grade
This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.
