High-speed differential hard metric connector

1 August 2001 Interconnection

The ERmet ZD is specifically designed for high speed differential signalling in telecoms applications at data rates of up to 5 Gbps. Erni's robust, high performance, modular connector system is also designed to be used in conjunction with the 2 mm hard metric (IEC 61076-4-101) family of connectors. It shares the chassis and board design features along with common layout references.

The connector family meets the electrical performance requirements of high speed, low voltage differential signalling, and is available in both surface mount and compliant pin, pressfit versions. The backplane module is a male pin header that has three mating levels. The ground shield and signal pins mate sequentially at 1,5 mm intervals.

The robust mechanical design and superior signal integrity are a result of the internal differential shielding scheme and the 'L'-shaped male shields. The inherently rigid male shields stand higher than the signal pins and surround each pair. An improved guidance feature completes the rugged mechanical design. An optimised grid design and SMT termination improve the RF characteristics. An easy and economical trace routing achieved by in-line design of signal and ground pins.
