Backplane Connector Supports Data Rates to 28 Gbps

15 February 2017

Impact™ zX2 Backplane Connector System. Source: Molex Impact™ zX2 Backplane Connector System. Source: Molex Molex has released the Impact™ zX2 Backplane Connector System, featuring high density and signal integrity (SI) performance, while supporting data rates of up to 28 Gbps in a modular design. The system utilizes Impel™ patented ground shielding and footprint technology to enhance SI performance.

Customers looking to upgrade their line cards to meet ever-increasing data rate requirements can now do so without making major revisions to their existing infrastructure. The zX2 system is backward compatible with standard Impact headers, allowing current Impact customers 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 to 95 Ohms, discontinuities are minimized throughout signal channels. Reduced-size compliant pins (0.36 mm) on both the backplane and daughter card modules optimizes the 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 ideal for applications in several markets, including telecommunications, data/computing, aerospace and defense and medical.
