The Tsi384TM is a high-performance forward bridge that connects the PCI Express (PCIe) protocol to the PCI and PCI-X bus standards. The Tsi384's PCIe Interface supports 1, 2, or 4 lanes. This enables the bridge to offer exceptional throughput performance up to 1 GBps.
The device's PCI/X Interface can operate up to 133 MHz in PCI-X mode, or up to 66 MHz in PCI mode. This interface offers designers extensive flexibility by supporting three types of addressing modes: transparent, opaque, and non-transparent.
High Performance
The Tsi384 incorporates deep buffering and a queuing architecture to minimize latency and maximize throughput. In addition to low-latency operation, the device supports a maximum payload size of up to 512 bytes to allow better throughput efficiency.
Low Power Consumption
The Tsi384 has typical power consumption of 1.3W, and incorporates power management to minimize power consumption during operation.
Transparent, Non-transparent, and Opaque Bridging
Transparent mode operation is available for efficient, flow-through configurations, while non-transparent bridging allows isolation between the Tsi384's PCIe and the PCI/X domains. Non-transparent bridging enables applications that use a processor on the secondary bus, such as intelligent storage adapters. Opaque mode provides semi-transparent operation for multi-processor configurations and enhanced private device support.
