Tsi382

PCI Express to PCI Bridge

Low Power Consumption

The Tsi382A 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 Tsi382A’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 and Non-transparent Bridging

Transparent mode operation is available for efficient, flow-through

configurations, while non-transparent bridging enables multi-host systems

and is used in applications such as intelligent adapter cards.

Typical Applications

The Tsi382A is suited to applications that need to bridge PCIe to downstream

PCI devices. Its flexibility, high performance, small footprint, and low power

consumption, make it ideal for a range of applications, including:

• Motherboards

• PC adapter cards (communications, graphics, imaging, and multimedia)

• Digital video recorders

• ExpressCards for laptop computers

• Multifunction printers

• Line cards and NICs
