Tundra Semiconductor is now in full production of its asynchronous PCI-to-PCI bridge. The Tsi350 is an industry-standard, 32-bit 66 MHz asynchronous PCI-to-PCI bridge fully compliant with PCI Local Bus Specification Revision 2.3. The bridge is drop-in, pin-for-pin and software compatible with industry-standard PCI bridges. The Tsi350 supports two PCI buses operating concurrently with sufficient clock and arbitration pins to support nine PCI bus master devices directly on its secondary interface.

The Tsi350 makes it possible to extend a system’s load capability limit beyond that of a single PCI bus by allowing board designers to add additional PCI devices or more PCI option card slots than a single PCI bus can support. The Tsi350 targets both new designs and existing board footprints that use 32-bit PCI-to-PCI bridges. Backed by Tundra’s world-class customer service and support, the Tsi350 is ideally suited for communications and networking equipment, video capture cards, embedded video recorders, multi-function printers, and network interface cards.
