VIA Velocity VT6120 Gigabit Ethernet Controller

The VIA Velocity™ VT6120 Gigabit Ethernet controller enables leading-edge performance in a highly integrated package, making it ideal for a diverse range of PC client or server LAN on Motherboard (LOM) applications. Integrating a feature laden MAC and Cicada's patented SimpliPHY™ transceiver, the VT6120 Controller is optimized for space constrained systems with a low power, low profile design.

Supporting 10/100/1000 Mbps triple-speed and full/half-duplex capability at all speeds, the integrated Cicada PHY is fully compliant to IEEE 802.3 (10BASE-T), 802.3u (100BASE-TX), and 802.3ab (1000BASE-T) standards. With Cicada's proven SimpliPHY™ design, VIA's Velocity controllers feature leading narrow band noise tolerance that delivers superior performance for real world PCBs and cables.

To minimize host-side CPU utilization, VIA Velocity Gigabit Ethernet Controllers adopt an adaptive interrupt scheme to reduce interrupts made to the processor, and maximize the use of packet bursts for efficient PCI bandwidth usage. The Velocity controllers can further offload tasks from the host CPU to improve the overall system performance with TCP/UDP/IP checksum, and TCP segmentation offloading.

To maximize network management features for the user, the VIA VT6120 includes sophisticated GigaCheck™ link management software that makes available comprehensive cable diagnostics, operating analysis, and status information greatly simplifying network management and troubleshooting.

To reduce system complexity and cost VIA Networking's Velocity Gigabit Ethernet controllers utilize a single 3.3V power supply, and also support advanced power management features.

Benefits of VIA Velocity VT6120

Highly Integrated Solution
10/100/1000 single chip solution that includes checksum offloading, jumbo frame support, a deep on-chip Tx/Rx packet buffer, and a full suite of management features including compliance with IEEE 802.3ab, 802.3x, 802.p, 802.1Q standards.

Integrated SimpliPHY™ Technology
Cicada's integrated SimpliPHYÔ technology ensures outstanding narrow band noise tolerance for long distance connections. Ideal for networks where poor connections or substandard cables are in operation.

Low Power
With a 0.15um design and 3.3V low voltage required power supply, VIA's Velocity Gigabit Ethernet controllers fully support the latest ACPI, WoL, and PCI Power Management standards. The controllers will also automatically switch from 1000Mbps to 100 or 10Mbps in standby mode, further reducing power consumption.

GigaCheck™ Software Interface
A full software suite that enables comprehensive cable diagnostics, operating analysis, and status information. The software also can provide information regarding connection speed, link quality, cable analysis, and VLAN management- all in an easy to use attractive interface.
