Device Overview
The IDT Tsi382 is a high-performance bus bridge that connects the
PCI Express protocol to the PCI bus standard. The Tsi382’s PCIe Inter-
face supports a x1 lane configuration, which enables the bridge to offer
throughput performance of up to 2.5 Gbps per transmit and receive
direction.
The device’s PCI Interface operates up to 66 MHz, and offers
designers extensive flexibility by supporting three addressing modes:
transparent, opaque, and non-transparent.

Tsi382 Evaluation Board Product Brief
Smallest Footprint
The Tsi382 BGA package has the smallest footprint of any PCIe-to-
PCI device on the market. The device is offered in a 10 x 10 mm
package with a standard 0.8 mm ball pitch, making it ideal for PCI
ExpressCard applications or similar designs that have limited compo-
nent space. For cost-sensitive applications, the Tsi382 is also available
in a LQFP package.
In addition, by providing sufficient clock outputs for up to four PCI
devices, board space is further reduced by eliminating the need for an
external clock buffer.
Low Power Consumption
The Tsi382 has typical power consumption of less than 0.7W, and it
incorporates advanced power management modes to minimize
consumption during operation.
High Performance
In addition to low-latency operation, the Tsi382’s superior queueing
architecture and rich feature set allow designers to optimize their overall
system performance. Features such as short-term caching also enable
designers to tune the device’s performance for different applications.
Transparent, Non-transparent, and Opaque
Bridging
Transparent mode operation is available for efficient, flow through
configurations. Non-transparent bridging also enables multi-host
systems and is used in applications such as intelligent adapter cards.
Opaque mode provides semi-transparent operation for multi-processor
configurations and enhanced private device support.

Typical Applications
The Tsi382 is suited to applications that need to bridge PCIe to
downstream PCI devices. Its flexibility, high performance, small foot-
print, and low power consumption, make it ideal for a wide range of
applications, including:
•
Digital video recorders
•
ExpressCards for laptop computers
•
Motherboards (PC, ultra-mobile PC, server, SBC, industrial PC)
•
PC adapter cards (communications, graphics, imaging, and
multimedia)
•
Multifunction printers
•
Line cards and NICs
