APPLICATIONS
• Universal line card for multi-service
provisioning platforms and
SONET/SDH add-drop muxes providing
10/100/1000 Mbps Ethernet, Fibre
Channel, FICON, ESCON and DVB-ASI
• Link aggregation and trunking between
10 ports of 10/100/1000 Ethernet
and 1 port of 10G Ethernet
• Enterprise and Metro Ethernet switches
• Aggregation for WDM and DWDM
transport
• 10G Ethernet Uplink for Switches
SPECIFICATIONS
• Reference frequency of 156.25 MHz
±100 ppm driven to on-chip
synthesizers as either single-ended
LVTTL or differential LVPECL
• Data transmission clocks options of
312.5 MHz or 390.625 MHz
• Data receive clock speeds from
311 MHz to 450 MHz
• Power supplies of 1.8V, 2.5V and 3.3V
required
10G Multi-Protocol Multi-Rate Metro Data
Services Media Access Controller (MAC)
Making next-generation networks a reality.
The VSC7331VH is an essential component enabling cost-effective,
new-generation, metropolitan network markets
• Business Continuance Networks
• Terrestrial Broadcast Networks
• Metro Virtual Private Networks
When used with the VSC9118, the VSC7331 creates a powerful
solution for a Universal Line Card that leverages advances in
SONET/SDH networks for Metro Area Networks. The VSC7331 makes
optimal use of the Virtual Concatenation and LCAS capabilities
provided in the VSC9118 to facilitate optimum bandwidth utilization.
Because each port can be independently congured for any of the
supported protocols in the Universal Line Card (10/100/1000 Mbps
Ethernet, Fibre Channel, FICON, ESCON or DVBASI), Carriers and
Services Providers do not have to stock multiple versions of this line
card. Such exibility is central to offering cost-effective solutions for
Carriers and Service Providers ensuring competitive deployment of
technical and nancial resources.
The Vitesse Mapper and MAC components come together seamlessly to
offer an optimal solution for cost-effective development of applications
addressing high-density, exible, client interfaces through OC-192
SONET/SDH connectivity with STS-1 granularity. The intelligence and
exibility of the VSC7331VH make it a central building block for metro
data services equipment and networks.
The Vitesse VSC7331 is a 10-Gigabit, Multi-Protocol, Multi-Rate
Metro Data Services Media Access Controller (MAC). Each port can be
independently congured to support any of the supported data
streams, including, Ethernet (10/100/1000 Mbps), Fibre Channel
(1-Gigabit), FICON, ESCON or DVB-ASI. Alternatively, the VSC7331
can be congured for a single 10- Gigabit Ethernet port.
Line interfaces include Ethernet SERDES, TBI, RGMII, MII or XAUI.
The Data Interface is an OIF Standard SPI-4.2 10-Gigabit, multi-
channel interface. Key features include Metro Area Flow Control and
Advanced Port Aggregation.
