VSC7280
Dual XAUI – Dual XGMII Octal 0.95 Gbps to 3.25 Gbps Transceiver
GENERAL DESCRIPTION:
The VSC7280 is a Dual XAUI – Dual XGMII
Transceivers 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 eight channels of serial transmitter/receiver pairs, these
transceivers can deliver a duplex data rate of greater than 40
Gbps. These serial channels can be configured for independent
operation, as two fully 10GbE/10GFC compliant XAUI (10 Gigabit
Attachment Unit Interface) serial buses, or a combination thereof.
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
these devices. 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 XGMII/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
VSC7280 have the functionality to support these common rates
simultaneous with a single external reference clock.
Whether the application is a high-speed backplane, chassis-to-
chassis communication or an optical link, these devices can
provide the flexibility and reliability required in today’s high-end
Data Communication systems.
MODES OF OPERATION:
The VSC7280 allow for flexibility in multiple systems
environments.
