描述
The TSI148 is the latest-generation component in IDT’s industry-leading, high-performance VMEbus system interconnect product family. The device is fully compliant with the 2eSST and VME64 Extension standards which allow designers to take advantage of the higher performance VME protocols, while preserving existing investment in VME boards that implement legacy protocols. TheTSI148 increases a system’s usable bus bandwidth through a local bus interface designed for the PCI/X processors and peripherals that support either a 66 MHz PCI bus or a 133 MHz PCI-X bus interface.
