• Supports up to nine PCI bus masters on

the secondary interface

• Ten independent secondary clock

outputs to the secondary slots

• Primary and secondary interfaces can be

operated using asynchronous clocks

• Secondary clock can either be derived

from the input primary clock or supplied

by an external clock source

• Secondary clocks can be masked

through the GPIO interface during

system’s load capability limit beyond that of a

single PCI bus by allowing motherboard

designers to add more PCI devices or more PCI

option card slots than a single PCI bus can

support.

The Tundra Semiconductor Tsi350 is a PCI-to-PCI bridge that is fully

compliant with

PCI Local Bus Specification, Revision 2.3.

The Tsi350 has

sufficient clock and arbitration pins to support nine PCI bus master devices

directly on its secondary interface.

The Tsi350 allows the two PCI buses to operate concurrently. This means that

a master and a target on the same PCI bus can communicate while the other

PCI bus is busy. This traffic isolation may increase system performance in

applications such as multimedia.

The Tsi350 makes it possible to extend a system’s load capability limit beyond

that of a single PCI bus by allowing motherboard designers to add more PCI

devices or more PCI option card slots than a single PCI bus can support.

The Tsi350 has two identical PCI Interfaces that each handle PCI transactions

for its respective bus, and, depending on the type of transaction, can act as

either a bus master or a bus slave. These interfaces transfer data and control

information flowing to and from the blocks shown below.

PCI-to-PCI Bridge

Benefits

• Extend PCI load capability

•

Typical Applications

Option card designers can use Tsi350 to implement multiple-device PCI

option cards. Without a PCI-to- PCI bridge, PCI loading rules would limit

option cards to one device. The

PCI Local Bus Specification

loading rules limit

PCI option cards to a single connection per PCI signal in the option card

connector. The Tsi350 overcomes this restriction by providing, on the option

card, an independent PCI bus to which up to nine devices can be attached.

Figure 2 shows how the Tsi350 enables the design of a multi-component

option card or expand exisitng PCI buses.
