Tsi384 PCIe to PCI/X Bridge Product Brief Device Overview The IDT Tsi384 is a high-performance bus bridge that connects the PCI Express (PCIe) protocol to the PCI and PCI-X bus standards. Clocking/ EEPROM The Tsi384s PCIe Interface has superior performance and supports PCIe Interface (x4) Reset Controller 1, 2, or 4 lanes. This enables the bridge to offer exceptional throughput performance of up to 1 GBps. The devices 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 Posted Posted UpstreamUpstream extensive flexibility by supporting three types of addressing modes: Writer Queue Buffer transparent, opaque, and non-transparent. Interrupt Mux Logic Power Non- Non- Handling Mgmt Posted Posted Low Power Consumption Buffer Queue Posted Posted Writer The Tsi384 has typical power consumption of 1.3W, and incorporates Queue Config Error Buffer Mux Logic Registers Handling advanced power management to minimize power consumption during Non- Non- operation. In addition to supporting D0, D3 hot, and D3 cold power Posted Posted DownstreamDownstream Buffer Queue management modes, the device permits unused PCIe lanes to be powered off automatically or by configuration. Transparent, Non-transparent, and Opaque Bridging PCI/X PCI/X Interface JTAG Arbiter Transparent mode operation is available for efficient, flow-through configurations, while non-transparent bridging allows isolation between 80E1000 BK001 01 (Tsi384) the Tsi384s PCIe and the PCI/X domains. Non-transparent bridging also enables multi-host systems and is used in applications such as storage Figure 1 Tsi384 Block Diagram adapters. Opaque mode provides semi-transparent operation for multi- processor configurations and enhanced private device support. Features General High Performance PCI Express to PCI/PCI-X Forward bridge The Tsi384 incorporates many advanced PCIe protocols that Transparent, Non-transparent, and Opaque modes increase system performance, including: Lane Reversal and Polarity Low latency Superior queuing and buffering architecture Inversion, end-to-end CRC, ASPM L0 link state power management, maximize throughput and minimize latency and Hot Plug. In addition to low-latency operation, the device supports a Compliant with the following specifications: maximum payload size of up to 512 bytes to allow better throughput effi- PCI Express Base 1.1 ciency.
