Tsi148™ PCI/X-to-VME Bridge
Features The Tundra Semiconductor Tsi148 device is the next generation component in our industry leading, high performance VMEbus system interconnect VMEbus Interface product family. Tsi148 is fully compliant with the 2eSST and VME64 • Standards supported: Extension standards. This enables you to take advantage of the higher – Legacy protocols to protect existing performance VME protocols, while preserving your existing investment in VME investment VME boards that implement legacy protocols. – VME64 Extensions Tsi148 increases a system’s usable bus bandwidth because its local bus – 2eVME and 2eSST protocols to bring interface is designed for the next generation PCI/X processors and support for higher bandwidth peripherals that support either a 66 MHz PCI bus or a 133 MHz PCI-X bus • Full VMEbus system controller interface. functionality • Interrupt and interrupt handling Tsi148 eases design constraints of VME Single Board Computers (SBCs) by capability requiring less board real estate and power than the previous generation of • Flexible register set; programmable VME-to-PCI/X bridge components. from both the PCI/X bus and VMEbus These capabilities make Tsi148 a key building block of the VME Renaissance and of next generation VME single board computers. Tsi148 VME-to-PCI/X bridge provides a 4x Block Diagram increase in usable bus bandwidth over existing solutions. IEEE1149.1 Boundry Scan

Benefits VME Renaissance • Increased bandwidth The VME Renaissance is a term defined by MotorolaTM that describes an intense – 4x increase in usable system bus period of intellectual activity and technology infusion focused on the VMEbus. bandwidth over current solutions The VME Renaissance is a period of innovation and performance improvement • Less power required than existing which maintains backwards compatibility to legacy VMEbus standards. This devices due to reduced voltages compatibility requirement protects existing customer investments. – 3.3V I/O supply The VME Renaissance gives VME a faster parallel backplane interconnect, a – 1.8V Core supply switched serial interconnect on the backplane coincident with the traditional • Small device footprint parallel interconnect, point-to-point mezzanines on the cards and many – 40% less board space required than other significant innovations. existing products • Reliable customer support with Typical Applications experience supporting the VME community for the past decade. Tsi148 can be used on VME-based Single Board Computers (SBC) that employ PCI/X as their local bus, as shown in the accompanying diagram. These SBC cards support a variety of market segments, including: Tundra Semiconductor is the world leader in telecommunications, datacommunications, medical, industrial automation, VME interconnect technology. and military equipment.
