PI7C9X130 (NRND)

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 PI7C9X130 is composed of one x4 PCI Express port and one standard 64- bit /133 MHz PCIX port. The versatile PI7C9X130 is capable of both “forward” and “reverse” bridging. In “forward” mode, the PI7C9X130 is configured with the PCI Express port on the primary and the PCI/PCIX port on the downstream side. The typical usage in this configuration is to “bridge” legacy PCI/PCIX product to PCI Express systems. In “reverse” mode, the PI7C9X130 is configured with the PCIX 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/PCIX systems.
