TSI310A-133CE

Specialized Overview

The TSI310A-133CE is a 64-bit PCI-X bus bridge operating at speeds up to 133 MHz with transfer rates reaching 1 GBps. It connects two electrically separate PCI-X bus domains, allowing concurrent operations on both buses for optimal utilization and hierarchical I/O expansion. The device supports configurations of PCI or PCI-X mode on either bus in any combination. It employs a 3.3V signaling environment and utilizes two phase-locked loops for clock domains. The architecture includes extensive buffering mechanisms, such as two 4-Kbyte burst read buffers and two 1-Kbyte posted write buffers, facilitating efficient data transfer and multi-threaded operation.

Specialized Feature Summary

• Supports full PCI 2.2 backward compatibility while enabling migration to the faster PCI-X protocol.
• Enables concurrent primary and secondary bus operation to increase system performance through simultaneous upstream and downstream transactions.
• Features extensive built-in buffering and prefetching mechanisms for efficient data transfer between buses.
• Allows flexible configuration of PCI or PCI-X mode on either bus in any combination.

Specialized Applications

• Server RAID controllers
• External RAID systems
• Fibre Channel host bus adapters
• Network interface cards
• Embedded computing

Specialized Procurement Notes

Verify the component origin, as the documentation indicates Integrated Device Technology (IDT) as the original manufacturer before Renesas Electronics Corporation acquisition. Confirm the specific suffix 'A-133CE' matches the required package type and electrical specifications against the official datasheet. Ensure compliance with the Non-Disclosure Agreement terms if accessing restricted planning materials. Validate that the 304-pin HPBGA package dimensions align with your PCB layout requirements.

Specialized Selection Notes

Select this bridge when designing systems requiring high-speed interconnectivity between PCI and PCI-X domains. It is suitable for applications needing concurrent bus operations and hierarchical I/O expansion. Consider its 3.3V I/O levels and 64-bit width for bandwidth requirements. Evaluate the need for optional features like opaque addressing or secondary side device privatization based on embedded processor integration needs.

Specialized Part Context

The TSI310 series was originally developed by Integrated Device Technology (IDT). IDT was acquired by Renesas Electronics Corporation, which now manages the product line. This bridge chip serves as a critical component for upgrading legacy PCI-based systems to the more robust PCI-X environment, maintaining compatibility with older standards while offering enhanced throughput capabilities.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Designers should consult official Renesas or IDT documentation for potential cross-references or newer generations of PCI-X bridges.
