Miniature connectors tout up to 2Gb/s in rugged environments

Keywords:nano-miniature connector? cable system? Mil-spec-circular connector?

Omnetics has introduced its Nano miniature connectors that are designed and connected to impedance-controlled cable systems. According to the company, the solutions offer high-quality signal integrity for high-speed Gigabit signal processing needs between components and systems in highly rugged environments.

Less space and lower weight are additional benefits when using the nano-miniature connectors. Previous versions of micro-connectors at 0.050in pitch, and even larger Mil-spec-circular connectors such as 38999 have been used, but are holding back the miniaturisation as well as the overall portability of many systems. Omnetics employs its standard line of nano-sized Bi-lobe connectors at 0.025in pitch that are mated with high-speed cable using differential signal hook-up methods that include dedicated drain wires to achieve the highest speeds possible. Up to and over 2Gb/s are being achieved as cable lengths are maintained at a minimum length, and impedance matching is managed to retain the best possible performance. The key to achieving good performance lies within a unique wiring methodology, precision processing of the interface between cable and connectors, as well as through the understanding of high-speed digital transmission technology, noted the firm.

Omnetics maintains a high-speed modelling and testing facility that is staffed with experienced engineers to work directly with the designer. This attention to detail early in the design stage helps save you time and money, while achieving the highest signal integrity performance needed for the application. Working with Omnetics design team, the company recommend using surface-mount nano-connectors as the main interface to the printed circuit boards to maximise signal launch from the boards to the interconnections as opposed to thru-hole. Design options are available and can be discussed as new design sizes, shapes and challenges arise.

EMI needs serious attention as digital speeds increase and components are physically squeezed into smaller and tighter environments. Cable shielding and drain-wire methods are changing too, mainly as a way of protecting the signals being sent from one end to the other. The all-metal shells and shielded cable in Omnetics nano-connectors also flaunt excellent source of ground management.
