Product Description

As one of the leading PCI Express Solution Providers, Diodes is committed to introducing a line of performance tuned PCI Express Bridge Products. The PI7C9X110 is composed of one x1 PCI Express port and one standard 32- bit / 66MHz PCI port. The versatile PI7C9X110 is capable of both “forward” and “reverse” bridging. In “forward” mode, the PI7C9X110 is configured with the PCI Express port on the primary and the PCI port on the downstream side. The typical usage in this configuration is to “bridge” legacy PCI product to PCI Express systems. In “reverse” mode, the PI7C9X110 is configured with the PCI port on the primary and the PCI Express port on the downstream side. The “reverse” configuration will be mainly used to “bridge” new PCI Express products to legacy PCI systems.
