Signal Integrity for High Speed MicroTCA Systems

The implementation of real-time applications requires a powerful infrastructure for the data transfer which has to distinguish itself by large transmission bandwidths at least possible delays and minimum risks of loss. High data transfer rates are required mainly by modern telecommunication applications. This field extends increasingly towards sophisticated multimedia applications and demanding industrial fields of application, such as machine and process control. In particular the MicroTCA standard contributes decisively towards this development, thanks to its high degree of modularity. In this connection, signal integrity is of great importance. As we will see in the following, certain reflections on 3 GHz systems have to be made that take into consideration the signal behavior of up to 15 GHz! (-More-)

VITA News

Three specifications have completed working group ballots: VITA 41.6 VXS 1X Gigabit Ethernet Control Channel Layer, VITA 53 COTS Commercial Market Surveillance Activities and VITA 46.9 XMC and PMC Mezzanine IO Mapping on VITA 46.

PICMG News

The Rugged MicroTCA effort is continuing to draw between 30 and 40 companies almost every week.

The PICMG Interconnect Channel Characterization Committee (PICCC) has a specification that currently is at a 0.3a draft level.

MicroTCA Fully Redundant Subrack Backplane


The backplanes have a 20 layer structure and guarantee optimum signal integrity. They support all FRU (Field Replaceable Unit) functions. The high-speed routing is effected by means of Dual Star technology, the high-speed connectors used are developed especially for high-speed data transfer. Two options are available for telecommunication and non-telecommunication applications.

MicroBox Backplane


The backplane for the MicroBox (http://www.nextgenbackplanes.com/microbox.htm) features slots for 6 AMC, 1 PM (Power Module), 1 MCH (MicroTCA Carrier Hub), 1 JSM (J-TAG Switch Module) and 2 CUs (Cooling Units). Compression mount connectors are used in the backplane for increased reliability and superior (easier and more flexible) routing. If a connector is damaged in the field, it has two screws securing it in place that can be easily removed for replacing the connector.
