Forward – PCIe primary, PCI secondary
Product:
PCI Express-to-PCI Reversible Bridge
Part Number:
PI7C9X110
Product Description
As one of the leading PCI Express Solution Providers,
Pericom 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.
