11.5 Gbps 8 × 8 Crosspoint Switch
Vitesse’s multichannel 11.5 Gbps crosspoint switch provides a cost-effective solution for high-speed copper
interconnects
The VSC3308 is the industry’s highest performance signal integrity
crosspoint solution. The VSC3308 is uniquely capable of addressing a wide
array of routing, switching, and signal integrity issues across storage, blade
server, video distribution, telecommunications, and Ethernet applications.
Featuring an 8 × 8 non-blocking, multicasting switch core with ports running
at any rate up to 11.5 Gbps, the VSC3308 architecture provides
protocol-transparent operation, allowing each channel to run independently.
The VSC3308 supports a wide frequency range and virtually all data
protocols.
The VSC3308 incorporates Vitesse’s fourth-generation input equalization
and pre-emphasis I/O capability for the industry’s highest speed and
protocol requirements. The device can perform signal fanout, loopback, and
protection switching. It can also regenerate signals severely compromised
by transmission losses. Vitesse’s equalization works independently of the
data rate, providing highly effective compensation for deterministic jitter
across a wide range of high-speed interconnect applications.
