Backplane connector system maxes signal integrity at 28 Gbps
Designers tasked with upgrading line cards to meet ever-increasing data rate requirements can, Molex says, now do so without making major revisions to their existing infrastructure. The zX2 system is backward compatible with standard Impact headers, allowing current Impact users to keep their existing architecture in place while upgrading their chassis’ data rates.
A common-ground structure improves crosstalk isolation, resulting in increased near-end crosstalk (NEXT) margin. Tuned to lower functional impedance of 95 Ohms, discontinuities are minimised throughout signal channels. Reduced-size compliant pins (0.36 mm) on both the backplane and daughtercard modules optimises PCB footprint, which helps to further enhance the SI performance of the connector system by reducing impedance in the footprint.
The Impact upgrade, Impact zX2, is aimed at applications in markets including telecommunications, data/computing, aerospace and defence, and medical.
