Barrington-Il™ — 24 × 10/100/1000 and 2 × 10G Ethernet MAC with SPI-4.2 and XAUI Host Interfaces
Schaumburg-Il™ — 12 × 10/100/1000 and 1 × 10G Ethernet MAC with SPI-4.2 and XAUI Host Interfaces
GENERAL DESCRIPTION:
Barrington-II (VSC7344) is an advanced Ethernet
MAC containing 24 10/100/1000 Ethernet ports with
integrated SGMII and 100/1000 optical
serializers/deserializers. The host interface can be

VSC7346
configured as SPI-4.2, one XAUI, or two XAUI
interfaces. Each SPI-4.2 and XAUI host interface
uses a SPI-4.2 status channel for flow control. To support the high
oversubscription factor, the Barrington-II has a set of advanced QoS
features.
When using the SPI-4.2 host interface, both XAUI ports are available for
use as 10 gigabit Ethernet line ports.
In addition to Barrington-II, Vitesse offers Schaumburg-II (VSC7346), an
advanced Ethernet MAC containing 12 10/100/1000 Ethernet ports. It has
the same features and functionality as Barrington-II.
