Tundra Tsi308 HyperTransport to PCI-X Bridge  from 

Product Type: I/O Bridge

The Tundra Tsi308" is a HyperTransport" to PCI-X Bridge designed for cost and power sensitive MIPS processor based applications in communications, networking, and entry-level storage systems. Each HT port operates at a frequency of up to 600 MHz DDR for both transmit and receive directions and sustains a total aggregate bandwidth up to 2.4 Gbit/s per 8-bit bidirectional HyperTransport port. Each Tsi308 HyperTransport port can be 2, 4, or 8 bits wide in both transmit and receive directions. For increased flexibility, the Tsi308 supports one 64-bit, PCI/X, or 2-32 bit PCI/X configurable ports. A fairness algorithm allocates bandwidth among devices, thereby eliminating starvation of bridges at the end of the chain. Up to 31 devices can be daisy-chained to build higher capacity systems with multiple PCI/X buses and HT-based peripherals.

Tundra Tsi301 HyperTransport to PCI Bridge
The Tundra Tsi301" is a performance optimized HyperTransport" bridge designed for use with MIPS processors focusing on power and cost. The Tsi301 supports 64-bit, 66-MHz PCI operations and implements two, bidirectional 8-bit HT interfaces that provide 800 Mbyte/s of bandwidth in each direction. Up to 31 devices can be daisy-chained to build higher capacity systems with multiple PCI busses and HyperTransport-based peripherals.
