The on-board VIA Velocity VT6122 Gigabit Ethernet Controller
The VIA Velocity™ VT6122 Gigabit Ethernet controller enables leading-edge
performance in a small 14x14mm 128-pin LQFP package, optimized for 32-bit PCI
applications in space-constrained systems. Integrating a feature laden MAC and
Cicada's patented SimpliPHY™ transceiver, the VT6122 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 Networking'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.
Applications
The Velocity VT6122 controller is optimized for 32-bit PCI client-end applications.
Its small form factor 14x14mm, 0.4mm pin-pitch, 128-pin LQFP package provides a
low pin count body size that helps simplify signal routing, minimize board routing
area, resulting in a cost-effective board implementation. Furthermore, to allow a
flexible Gigabit Ethernet (10/100/1000-Mbps) or Fast Ethernet (10/100-Mbps)
implementations on the same board, VIA Networking offers a number of
configuration options integrating our wide range of Ethernet IC options.
