10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER

Ethernet transceiver

- Less than 700 mW per port

- Wake on LAN support

- Advanced power management

- Cable-plant analyzer function detects cable plant impairments

- Link quality indication LED

- Automatic detection and correction of wiring pair swaps, pair skew,

and pair polarity

- Automatic MDI/MDIX crossover at all speeds

•

Simplifies system and board design.

- Reduced I/O pin requirements with RGMII (over 50%).

- Clock timing can be adjusted to eliminate board trace delays

required by the RGMII specification.

•

Provides interoperability with IEEE standard devices operating at 10,

100, and 1000 Mbps at half- and full-duplex.

•

Lowers system BOM cost and simplifies system design.

•

Requires no airflow or heatsink.

•

Provides compliance with PCI 2.2 and PC99/PC2000.

•

Eases system level debug.

•

Reduces system design constraints to meet EMI emissions standards.

•

Cable diagnostic function characterizes cable plant condition and

immediately indicates cabling issues.

- Prevents erroneous equipment return due to bad cable plants.

- Prevents manufacturing fall-out due to bad cable plants.

•

High CESD tolerance prevents equipment damage and return.

•

Operates with larger packets for wider range of packet protocol

support and improved efficiency.

•

Ease of manufacturing with JTAG support, simplified power supply,

and multiple MAC interfaces.
