Product Description

The PI7C9X111SL is the latest addition to the PCI Express Bridge SlimLine family of solutions. With the PI7C9X111SL, users can expect a x1 PCI Express to 32bit/66MHz PCI Reversible bridge with high performance, very low power consumption, and a small footprint. PI7C9X111SL offers the most effective forward & reverse bridging solution to platforms with high bandwidth requirement. The typical usage for this device is high volume applications requiring a “bridge” from legacy PCI products to new PCI Express based systems, or applications requiring a “bridge” from new PCI Express based devices to legacy PCI systems. The PI7C9X111SL is a versatile device that can be used in applications including desktops, graphics cards, combo cards, PC peripherals, MFP Printer and video surveillance systems.
