The TSI108 host bridge for PowerPC processors supports PCI-X, DDR2-400 SDRAM, Gigabit Ethernet, and Flash. The TSI108 is optimized for customers in the wireless infrastructure, storage networking, network access, printer, military, and industrial automation markets. Its flexible configuration options allow designers to develop their systems quickly and efficiently. It minimizes active power by disabling unused ports and clocks, while its integrated Clock Generator saves power over discrete devices.
