Overview of Tsi148
The IDT Tsi148 device is the next generation component in our industry leading, high
performance VMEbus system interconnect product family. Tsi148 is fully compliant with the
2eSST and VME64 Extension standards. This enables you to take advantage of the higher
performance VME protocols, while preserving your existing investment in VME boards that
implement legacy protocols.
Tsi148 increases a system’s usable bus bandwidth because its local bus interface is designed
for the next generation PCI/X processors and peripherals that support either a 66 MHz PCI
bus or a 133 MHz PCI-X bus interface.
Tsi148 eases design constraints of VME Single Board Computers (SBCs) by requiring less
board real estate and power than the previous generation of VME-to-PCI/X bridge
components.
These capabilities make Tsi148 a key building block of the VME Renaissance and the
development of next generation VME single board computers.
