Vitesse further noted that its VSC3144-11 crosspoint features a non-blocking switch matrix that delivers 1.656 Terabit per second (Tbps) switching capacity. Compatible with the previously announced 6.5G and 8.5G versions, the VSC3144-11 enables a migration path for existing customers as they upgrade network routers and data center cross connect systems to higher capacity and bandwidth levels. Used together, these crosspoints enable low-latency, fully non-blocking switching capability on line cards and switch cards that are pervasive in Core, Metro, and Enterprise environments.
Vitesse proactively brought to market the VSC3144-11, thereby addressing the "perfect storm" convergence around 10 Gbps in telecommunications, Enterprise, and storage networks. The device supports a frequency range up to 11.5 Gbps encompassing virtually all data protocols, including GbE, XAUI, Reduced XAUI (RXAUI), 10 GbE, SONET/SDH and OTN protocols, InfiniBand as well as services such as 8G Fibre Channel.
In addition, IEEE and ITU-T standards for 40G and 100G data rates include 4x10G and 10x10G interfaces, exacerbating the need for large asynchronous switching matrices at 10G data rates.
"There is a fundamental shift underway across Carrier and Physical Layer interconnects. Across the board, 10G is seen as a convergence point across multiple protocols. New signal integrity challenges come into play at these speeds and Vitesse is positioned to help customers overcome these barriers," said Juan Garza, product marketing manager at Vitesse. "Coupled with backwards compatibility to previous generation crosspoints for central switches and new offerings for line cards, Vitesse is delivering a migration path sure to take our customers to this new networking paradigm."
The device is footprint compatible to Vitesse's previous generation devices, allowing a pin-compatible speed upgrade path for customers using the Vitesse 4.25G VSC3140, 6.5G VSC3144, and 8.5G VSC3144-08. Other features of the VSC3144-11 include:
- DC-to-11.5 Gbps differential signal paths with protocol-independent operation
- Adjustable input signal equalization with per-channel and global control
- Adjustable output pre-emphasis with per-channel and global control
- Lowest power available at this bandwidth level with 21W power consumption
- Ability to power-down unused channels for applications needing only a subset of channels
The VSC3144-11 is offered in a 45 mm X 45 mm, 1.27 mm pin pitch, 1072-pin BGA package. Evaluation systems, samples and pre-production volumes are available, with production status expected in the fourth quarter of 2009.
