AdvancedTCA 3.1R2 compliant card connectors
The new specification increases system bandwidth by four times, allowing a single chassis to handle data transfers up to 10 terabits per second for full mesh designs. This translates into transporting and switching over 2 million High Definition video channels at the same time. The new specification defines the ERmet ZD and ERmet ZDplus connectors offered by Erni Electronics as the backplane interconnect and on the daughter cards. The ERmet ZD connector has been selected as the backplane interconnect for the PICMG 3.x (ATCA) industry standard. ERmet ZD connectors were developed for differential high-speed signal transmission in telecom and datacom applications with data rates of up to 10 Gbps and beyond. The ERmet ZD connectors use an optimal design that reduces signal interferences and offers ample room for routing channels.
The ERmet ZDplus connectors are based on the same mechanical design as the proven ERmet ZD. The ERmet ZD plus female connector used on the daughter cards is mating compatible with the ERmet ZD male connector (used on the backplane). This means that existing backplane designs do not require any changes to the layout on the backplane side if the system is to be upgraded to the new connector. Using the ERmet ZDplus data rates in the range of 15 Gbps and more are possible through a greatly improved crosstalk behavior and an optimized signal path that results from smaller PCB vias for the press-fit terminal of the female daughter card connectors.
