100 G AdvancedTCA

PICMG recently released Revision 3 of the PICMG 3.1 specification, which defines the use of Ethernet (and Fibre Channel) on the AdvancedTCA (ATCA) backplane. This important update increases the backplane bandwidth by 2.5 times, from 40 GB/s to 100 GB/s. ATCA remains the fastest open standard for communications applications; this increased bandwidth is critical for data-hungry applications like mobile video, which is becoming more important and pervasive every day.

Doug Sandy, chief architect at Artesyn Embedded Computing and the CTO for PICMG, said that “extending AdvancedTCA’s capabilities to support a backward-compatible 100 Gb Ethernet in a little more than one year of effort is an astounding feat if you consider the fact that the original channel was designed for much lower bandwidth when ATCA was originally conceived in 2001. This is a testimony to PICMG’s deep commitment to collaboration and our combined knowledge base in hardware platform management, high-speed digital communications, and embedded-computing technologies.”
