Precision-engineered VPX backplanes designed to the toughest performance standards are essential for the high-speed signal demands prevalent in today’s defense applications. Backplanes are indeed the communication backbones in embedded systems and must be designed to stringent signal integrity standards to ensure timely and accurate data transmission from module to module within a system. For payloads aligned to VPX and SOSA [Sensor Open Systems Architecture] standards, high signal integrity is critical to enable fail-safe operation as systems move to higher serial bit rates supporting 100G-baseKR4 Ethernet, PCIe Gen 4 protocols, and beyond.
