Device Overview
The IDT Tsi148 device is the next-generation component in our industry
leading, high performance VMEbus system interconnect product family.
The Tsi148 is fully compliant with the 2eSST and VME64 Extension
standards. This enables you to take advantage of the higher perfor-
mance VME protocols, while preserving your existing investment in VME
boards that implement legacy protocols.
The 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 of next
generation VME single board computers.
