VSC7281
Dual XAUI – Single XGMII Quad 0.95 Gbps to 3.25 Gbps Transceiver
GENERAL DESCRIPTION:
The VSC7281 is a Dual XAUI – Single
XGMII Transceiver tailored for 10 Gigabit
Ethernet (10GbE) and 10 Gigabit Fibre
Channel (10GFC) applications. The feature
set and flexibility of these devices make
them perfectly suited for Backplane and
other Serial Interconnect applications such as Serial Rapid
I/O, PCI Express and XAUI.
With four channels of serial transmitter/receiver pairs, these
transceivers can deliver a duplex data rate of greater than 20
Gbps. These serial channels can be configured for independent
operation, or as fully 10GbE/10GFC compliant XAUI (10 Gigabit
Attachment Unit Interface) serial buses. The parallel bus is fully
XGMII (10 Gigabit Media Independent Interface) compliant. When
independent channel operation is required, the parallel bus can
be configured for either 8- or 10-bit operation with the ability to
enable or bypass the internal 8B/10B encoders/decoders.
No additional external logic is required for the basic operation of
this device. However, for flexibility and systems adaptability, an
MDIO (Management Data Input/Output) interface is provided for
internal register access. These registers are MDIO compliant and
allow for monitoring and configuration of special modes for
diagnostics, BIST (Built-In-Self Test), and various control of
special channel features, such as pre-emphasis, cable
equalization, reduced output swing, loopback, signal detection
and XAUI port selection.
The flexibility of this device is not only seen in the MDIO register
programmable feature set, but also in a wide range of supported
frequencies. With a serial data rate that can range from 0.95
Gbps to 3.25 Gbps, this device supports multiple communication
applications such as Fibre Channel, InfiniBand, and Ethernet. The
VSC7281 has the functionality to support these common rates
simultaneous with a single external reference clock.
MODES OF OPERATION:
The VSC7281 allow for flexibility in multiple systems
environments.
