The Tsi308 is a high performance third generation HyperTransport™-to-PCI/X bridge capable of transferring data between the HyperTransport (HT) host port and the other HT port or the PCI/PCI-X port. It is designed for bandwidth-hungry and performance-intensive applications in communications, networking, servers, and storage systems.
The next generation Tsi308 HT-to-PCI/X bridge expands the possibilities of today’s systems architects by providing HT-based design options never possible before. 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 19.2 Gbit/s per 8-bit bidirectional HT port. Each Tsi308 HT port can be 2, 4, or 8 bits wide in both transmit and receive directions.
The 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.
