Introduction
82573 GbE controllers are single, compact components with integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) functions. These devices use PCIe* architecture (Revision 1.0a). For desktop, workstation, and value server network designs with critical space constraints, the 82573 enables a GbE implementation in a very small area.
Product Features
■ PCIe
— x1 PCIe interface on ICH7 or MCH devices
— Peak bandwidth: 2 Gb/s per direction
— Power management
— High bandwidth density per pin
■ MAC
— Optimized transmit and receive queues
— IEEE 802.3x compliant flow control with software controlled pause times and threshold values
— Caches up to 64 packet descriptors per queue
— Programmable host memory receive buffers (256 bytes to 16 KB) and cache line size (16 bytes to 256 bytes)
— 32 KB configurable transmit and receive FIFO buffer
— Mechanism available for reducing interrupts generated by transmit and receive operation
— Descriptor ring management hardware for transmit and receive
— Optimized descriptor fetching and write-back mechanisms
— Wide, pipelined internal data path architecture
■ PHY
— Integrated PHY for 10/100/1000 Mb/s full and half duplex operation
— IEEE 802.3ab auto negotiation support
— IEEE 802.3ab PHY compliance and compatibility
— DSP architecture implements digital adaptive equalization, echo cancellation, and cross-talk cancellation
■ Host Offloading
— Transmit and receive IP, TCP and UDP checksum off-loading capabilities
— Transmit TCP segmentation, IPv6 offloading, and advanced packet filtering
— IEEE 802.1q VLAN support with VLAN tag insertion, stripping and packet filtering for up to 4096 VLAN tags
— Descriptor ring management hardware for transmit and receive
■ Manageability
— Intel® Active Management Technology (Intel® AMT) support (82573E only)
— Alerting Standards Format 2.0 and advanced pass through support (82573E/V only)
— Boot ROM Preboot eXecution Environment (PXE) Flash interface support
— Compliance with PCI Power Management 1.1 and Advanced Configuration and Power Interface (ACPI) 2.0 register set compliant
— Wake on LAN support
■ Additional
— Three activity and link indication outputs that directly drive LEDs
— Programmable LEDs
— Internal PLL for clock generation that can use a 25 MHz crystal
— Power saving feature for the 82573L. During the L1 and L2 link states, the 82573L asserts the Clock Request signal (CLKREQ#) to indicate that its PCIe* reference clock can be gated
— On-chip power control circuitry
— Loopback capabilities
— JTAG (IEEE 1149.1) Test Access Port (TAP) built in silicon
■ Technology
— Lead-free 196-pin Thin and Fine Pitch Ball Grid Array (TF-BGA) package
— Operating temperature: 0° C to 70° C (with external regulators)
— Operating temperature: 0° to 55° C (with ondie 2.5V regulator)
— Storage temperature -40° C to 125° C -
