The Tundra Semiconductor Tsi382A is a high-performance bus bridge that connects PCI Express based devices to legacy PCI devices. The Tsi382A’s PCIe Interface 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 supports transparent and non-transparent addressing. The Tsi382A supports Legacy mode operation, which configures the device as a subtractive decode PCIe-to-PCI bridge.
