    Vitesse IC enables scalable, high-density 10G/40G/100G communication systems

    Feb. 2, 2010
    CAMARILLO, Calif. - FEBRUARY 2, 2010 - Vitesse Semiconductor Corp. in Camarillo, Calif., announced the availability of the VSC8248 Quad Interconnect integrated circuit (IC) for carrier and enterprise network application support.
    CAMARILLO, Calif. - FEBRUARY 2, 2010 - Vitesse Semiconductor Corp. in Camarillo, Calif., announced the availability of the VSC8248 Quad Interconnect integrated circuit (IC) for carrier and enterprise network application support. The device has four Clock and Data Recovery (CDR) channels with integrated Electronic Dispersion Compensation (EDC), four integrated transmit channels, and control circuitry for managing downstream modules. This IC enables users to increase capacity for storage, server, router, or optical transport equipment. Whether transporting traffic across a backplane, a line card, an optical fiber, or a copper cable, the VSC8248 provides signal integrity, speed flexibility ranging from 1 gigabits per second to 11.3 gigabits per second, integrated diagnostics for remote monitoring, fault isolation, and scalability to more than 100,000 ports. Increased bandwidth requirements are driving transitions to higher speeds and greater port densities supporting new standards including 10, 40, and 100 Gigabit Ethernet as well as 8 and 16 Gigabit Fibre Channel. To meet these demanding requirements, new communication systems and modules are implemented in highly parallel 4x10G, 10x10G, and 10x12G architectures. These new architectures require converged features demanding a wide range of data rates and protocols in the same chassis. Supported by Vitesse's FlexEQ EDC capabilities, advanced VScope remote waveform viewing technology, an extensive suite of self test (BIST) functions, and low jitter, fully-compliant 10G BASE-KR output drivers, the VSC8248 provides improved signal integrity in converged parallel applications, company officials say.“The newest members of the celebrated FlexEQ-based product family deliver compelling blends of features and functionality to meet the stringent requirements of the SFP+ and next-generation and legacy backplane markets,” says Gary Paules, product marketing manager for Vitesse. “The superior capabilities of the VSC8248 solidify Vitesse's performance lead across a number of applications while supporting the market trends toward higher density, converged protocols, and lower cost.”VSC8248 Seamlessly Supports Multiple Applications Quad SFP+ module support: Ideal for all SFP+ formats including passive copper modules up to 20 meters, the VSC8248 is an affordable choice to support multi-channel SFP+ host applications compliant to 10 Gbps SFP+ 10GBASE-SR, 10GBASE-LR, 10GBASE-LRM, SFF-8431, and 8.5G Fibre Channel FC-PI-4 specifications. The VSC8248 TX path KR output driver can be optimized for driving copper in a passive copper module application or for superior optical eye, including minimum jitter generation, in optical applications. Delivering BIST functions, along with loopbacks, reduces prototype development, time-to-market and overall manufacturing cost. Independent module management for all four of the SFP+ module formats greatly simplifies host circuit card design while reducing bill of material costs.The VSC8248 is available today in leaded and lead-free package versions. Volume pricing is available upon request.Vitesse: www.vitesse.com
