Tsi108 Host Bridge for Product Brief Device Overview The Tundra Tsi108 is an advanced host bridge for PowerPC processors that supports PCI-X, DDR2-400 SDRAM, Gigabit Ethernet, and Flash. The device contains numerous integrated features that enable customers to reduce system design complexity and system costs. As a result, the Tsi108 has the best price/benefits ratio on the market. The Tsi108 builds on a decade of Tundra design experience in PowerPC host bridging. It delivers industry-leading performance for customers in the wireless infrastructure, storage networking, network access, printer, military, and industrial automation markets. Enhancing System Performance The advanced Switch Fabric architecture of the Tsi108 allows designers to significantly enhance system performance. The Ethernet Controller and PCI-X Interface offer superior data transfer rates. In addition, CPU to memory performance is exceptional due to features like configurable port arbitration priority and queuing reads ahead of writes. Minimizing System Cost The Tsi108 feature set provides system designers with an array of integrated functionality to assist in lowering overall system cost, such as an integrated Clock Generator with spread-spectrum capabilities, a DDR2400 Memory Controller, and internal processor and PCI/X bus arbiters. Simplifying Design Tsi108’s flexible configuration options empower designers to develop their systems quickly and efficiently. Selection of PCI/PCI-X modes, an integrated Clock Generator, DDR2 support, and the ability to configure it as a PCI Host/Agent, all enable the Tsi108 to be used in a range of applications. The JTAG Interface also simplifies the debug process by allowing access to Tsi108’s registers without impacting active transactions. Effective Power Management The Tsi108 is the lowest power consuming host bridge on the market. It minimizes active power by disabling unused ports and clocks, while its integrated Clock Generator saves power over discrete devices. Its support for DDR2 provides memory power savings of up to 50 percent when compared with DDR. The Tsi108 also conforms to the PCI Bus Power Management Interface Specification.
