Crimson Samples its MSPP-on-a-Chip

Crimson Microsystems, a start-up based in Sunnyvale, California, began sampling its "Ruby" MSPP-on-a-Chip, targeted at fully SDH/SONET-compliant access edge Multiservice Provisioning Platforms (MSPPs) in a compact 1-4 RU chassis.


Crimson said its device replaces up to eight discrete components and includes all necessary framing, pointer processing, high and low order cross-connect and path termination functions for STM-1/4/16 (and equivalent OC-3/12/48) SDH/SONET systems. The chip features integrated support for both SDH/SONET line- and ring-based protection schemes and a 22.5 Gigabit cross connect. Ruby-based MSPPs could be deployed either directly on a SDH/SONET access ring or as customer-located equipment on SDH/SONET access links. Ruby can be configured to support a mix of STM-1/OC-3, STM-4/OC-12 and STM-16/OC-48 lines/rings. Ruby's pointer processor, path termination, and cross-connect simultaneously support any combination of both high and low order paths.


The chip is implemented in 0.13um, low-power CMOS and packaged in a thermally-enhanced FCBGA. Ruby said it already has several design wins, including Xalted Networks.


"Ruby is aimed at significantly reducing the cost and complexity of today's MSPP equipment, enabling carriers worldwide to expand existing infrastructure to support new services and bandwidth demands. These new demands are driven by triple play applications as well as next generation wireless and Ethernet-to-the-enterprise," said Paul Nahi, president and CEO of Crimson Microsystems.
