Tsi310 133-MHz PCI-X Bridge Product Brief Device Overview The IDT Tsi310 is a 64-bit PCI-X bus bridge that operates at speeds up to 133 MHz, and supports transfer rates up to 1 GBps. The PCI-X protocol is backward compatible with the PCI bus standard ensuring that legacy PCI-based systems are portable to the faster PCI-X environment. The Tsi310 connects two electrically separate PCI-X bus domains, allowing concurrent operations on both buses. This results in optimal use of the buses in various system configurations, and enables hierarchical expansion of I/O bus structures. The device also supports configurations of PCI or PCI-X mode on either bus, and in any combination. In addition, the Tsi310 provides extensive buffering and prefetching mechanisms for efficient data transfer between two buses, facilitating multi-threaded operation and high system throughput.
