Elma introduces 40G AdvancedTCA backplanes
Elma Electronics UK has announced the development of 40G AdvancedTCA backplanes, based on the design principles of IEEE 802.3-2008 and IEEE 802.3ba-2010 standards.
The devices feature a controlled impedance stripline design of 18 layers in a dual star routing configuration. Other features include dual shelf manager connectors in slot 0 for redundant IPMB implementation and up to 400W/slot 48VDC distribution to each slot.
According to Elma, the backplane results were achieved using extensive pre layout and post layout simulation studies. Signal integrity simulations performed at the company showed that 10Gbps/link performance could be achieved with reasonable costs and manufacturing processes.
For superior performance, Nelco 4000 13-SI high grade laminate material was used and the backplane was back drilled to minimise stub reflections. Test data is available upon request.
