PCI/X to VME Bridge

The IDT Tsi148™ is the highest bandwidth VME bridge available, providing PCI-X-to-VME 2eSST performance levels while maintaining backward compatibility with older standards.

As the VME chassis continues to evolve, Tsi148 provides the bandwidth required to connect together distributed computing elements. VME systems are using distributed processing elements like CPUs, NPUs, and DSPs in order to manage the thermal density and provide scalability. New standards like VXS and VPX are using RapidIO® interconnect as the data path but in parallel VME bus traffic will also increase because control plane bandwidth scales with data bandwidth.

The Tsi148’s decoupled architecture and proper buffer sizing allows a very large number of simultaneous transactions to take place. The device is also a full featured master/slave and system controller, which allows it to be used in any VME application. Its low power and small package size make it an ideal choice where space and power are concerns.
