|Vitesse Introduces Grooming Switches That Enable Lowest Cost,
Next-generation Access and Metro Equipment|
CAMARILLO, Calif. - Vitesse Semiconductor
Corp. announced two new additions to its industry-leading SONET/SDH Time Slot Interchange (TSI) grooming switch
family: the VSC9190, 50 Gbps TSI Switch, and the VSC9191, 100 Gbps TSI Switch. Both devices are targeted at
dramatically reducing power and complexity of SONET grooming applications, while simultaneously simplifying and
accelerating the system level design process. These devices reduce power requirements by more than 50% over
comparable solutions, and, by incorporating automatic protection switching and rate aggregation into a single
device, reduce board chip count by a factor of five, dramatically shrinking space requirements and lowering costs.
TSIs are a key building block in the $7 billion optical transport systems market. This market grew by 11% in 2004
and is forecasted to grow another 6% in 2005, as reported by the Dell’Oro Group. TSIs perform the necessary function
of deskewing, switching, and regenerating SONET/SDH signals at the STS-1/STM-0 level. The VSC9190 and VSC9191
address these complex requirements within Access and Metro equipment such as SONET/SDH Multiservice Switches, Add
Drop Multiplexers, Optical Switches, and DWDM Long Haul and Metro equipment.
These scalable TSIs
support dual rate 2.5 Gbps or 622 Mbps Input/Output (I/O) speeds, enabling high-speed 2.5 G links or compatibility
with existing 622 M equipment, and contributing to lower cost and power requirements. Their fully non-blocking
memory-based switch core simplifies system architectures and shortens overall development time with fast,
single-step programming that eliminates the need for complex programming algorithms.
and VSC9191 utilize bit-slicing technology to enable fabric configurations up to 1.36 Tbps using the lowest possible
chip count. This functionality routes traffic to and from scalable hubs based on Vitesse’s flagship VSC9295 340 Gbps
single-chip TSI. The devices also use 2.5 Gbps TFI-5 and 622 Mbps STS-12/STM-4 standards-based interfaces for
connecting with existing line cards, backplanes, and ASIC infrastructure.
“SONET isn’t dead,”
says Juan Garza, circuit switch product marketing manager for Vitesse. “The VSC9190 and VSC9191 are designed to
enable OEMs to dispel the myth that SONET switching equipment is expensive and difficult to build. Over a decade of
industry-leading expertise is built into every chip, allowing the system designer to focus their resources on other
tasks to get their product to market faster without the compliance and interoperability issues of home brewed
World Class Signal Integrity
The VSC9190 and VSC9191 feature Vitesse’s
industry-renowned signal equalization technology (EQÔ) for enhanced signal integrity in high-speed systems. Vitesse
EQ improves signal performance and reduces jitter associated with driving multi-gigabit signals across backplanes
and cables. By enhancing signal performance in systems, OEMs can improve data integrity and migrate to
next-generation serial interconnect speeds utilizing existing PCB, backplane, connector equipment and system
architectures. Vitesse’s flexible EQ settings utilize global programmable Input Signal Equalization (ISE) and output
pre-emphasis capabilities to improve signal clean up as well as line driver capabilities.
