VIA Rhine™ III VT6105M Fast Ethernet Controller

This product is available fully ROHS-compliant.

The VIA Rhine III VT6105M is a 10/100Mbps Fast Ethernet controller designed to provide system designers an easy to integrate single chip solution, with advanced management and power conservation features. Featuring a 3-in-1 design the VIA VT6105M integrates the physical, media, and management layers into a single chip.

Fully compliant with IEEE 802.3/802.3u 10BASE-T and 100 BASE-X standards, the VIA VT6105M has an advanced flow control scheme that provides full and half duplex support allowing data transfers at 200Mbps in full duplex mode. The VIA VT6105M employs a VIA-developed ASIC chip that optimizes data transfer between the chip and the PCI bus providing extensive trouble shooting and management capabilities, including auto MDI/MDIX configuration, remote bootability, and TCP/IP checksum to reduce CPU utilization. The VT6105M also contains advanced power management features for low power consumption including Wake on LAN (WOL), and a low power design.

Available as a single chip or in a PCI add in card, the VIA VT6105M is equipped with enhanced management features including priority queues to increase multimedia transfer speeds, fiber mode for fiber optic networks, and enhanced V LAN for improved network performance and security.
With its integrated design and excellent feature set the VIA VT6105M is ideal for integration into network controllers, network workstations, NICs, or LAN-on-motherboard solutions, providing a manageable, integrated controller to bring high speed Ethernet connectivity to the electronics of tomorrow.
