Configurable interconnects support multi-gigabit VME-based design

To help designers evolve VME-bus systems to take advantage of high-speed serial switched-fabric interconnects such as PCI Express and 10Gb Ethernet, Tyco Electronics is offering the MultiGig RT backplane interconnect family with support for VITA 41 (VXS) and VITA 46 (VPX) specifications.

The MultiGig RT1 and RT2 families support 141 signals per inch at data rates up to 3.125Gbit/s, and 113 signals per inch at data rates greater than 6.4Gbit/s respectively. MultiGig RT2 interconnects have actually been demonstrated at up to 10Gbit/s. Both families are also fully compatible with MP-based fibre-optic-array interconnects.

The interconnect system comprises modular, pinless connectors, which can be configured using custom printed-circuit wafers to implement signal and power connections meeting the required signal sequencing or power rating. Wafers can be manufactured specifically for differential or single-ended signalling. The impedance, propagation delay, and crosstalk of the connector can be altered to meet application-specific requirements.

The pinless design eliminates the pin field on backplane boards. Further features that save PCB complexity include an optimised footprint for easier layout and the use of 0.022-inch diameter vias to save fabrication costs.
