And it is the first connector system that meets the requirements of 100G ATCA technology. The high data transmission speeds and improved transmission response are primarily based on the reduced size of the signal termination, designed for vias with a diameter of only 0.30 mm. The diameter of the drilled hole for the shielded contacts is 0.46 mm. The fact that reducing the vias improves crosstalk motivated the further miniaturization of the press-fit area.
Communication technology indicates a growing trend toward increased data transmission speeds and bandwidths. This implies a significant need for data transmission via 100 Gigabit Ethernet (GbE). Typical applications include next-generation internet backbones, data centers, and cloud processing. The new ERmet ZDpro connectors meet the requirements and challenges of the critical interface between backplane and daughterboards in these high-speed systems.
ERmet ZDpro is based on the mechanical design of the well-known ERmet ZD and ERmet ZDplus families, maintaining the same dimensions. ERmet ZDpro connectors are compatible with ERmet ZD and ZDplus connectors. This means that no changes to the wiring of existing backplane designs are necessary if customers wish to upgrade their daughterboards as a first step before upgrading the entire system. However, modifications to the daughterboard wiring will be required when using ERmet ZDpro receptacles.
To fully utilize the performance of the new ERmet ZDpro family, controlled-depth drilling is recommended. By reducing the length of the track adaptation section and the corresponding "stub effect" through controlled-depth drilling, reflections and the overall Bit Error Rate (BER) of the connection are significantly reduced.
Availability:
The first products in the ERmet ZDpro family are the 4-pair right-angle female connector and the corresponding straight male connector with push-fit termination. Both will be available from September 2015. The connectors provide 40 signal pairs. Male connectors are available with different contact lengths (3.8 mm or 5.3 mm). The standard versions with 3.8 mm contacts offer optimized impedance, while the male connectors with 5.3 mm contact lengths provide a 1.5 mm longer solder length, reaching 2.9 mm.
