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 inte-

grated functionality to assist in lowering overall system cost, such as an

integrated Clock Generator with spread-spectrum capabilities, a DDR2-

400 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 transac-

tions.

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.
