82546GB Dual Port Gigabit Ethernet Controller Networking Silicon Datasheet, Product Features include PCI/PCI-X, MAC, PHY, Host Offloading and Manageability functions
The Intel 82546GB Dual Port Gigabit Ethernet Controller is a single, compact component integrating two full Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. It supports 1000BASE-T, 100BASE-TX, and 10BASE-T applications and provides a 64-bit wide PCI 2.3 and PCI-X 1.0a compliant interface operating up to 133 MHz.
| Interface Support | PCI/PCI-X —PCI-X Revision 1.0a support for frequencies up to 133 MHz |
|---|---|
| MAC Compliance | IEEE 802.3x compliant flow control support |
| Internal Data Path | Wide, optimized internal data path architecture (128 bits) |
| FIFO Buffers | Dual 64 Kbytes configurable Transmit and Receive FIFO buffers |
| PHY Operation | Integrated PHY for 10/100/1000 Mbps full and half duplex operation |
| Host Offloading | Transmit and receive IP, TCP and UDP checksum off-loading capabilities |
