PCIe / PCI Bridges

PCIe-to-PCI / PCIX Bridge product capable of Forward or Reverse bridging are offered by Diodes. “Forward” (PCIe-to-PCI/PCIX) mode provides an effective turn-key bridging solution between PCI Express Host on the primary side and PCI/PCIX Peripheral Devices as the secondary interface. The “Reverse” (PCI / PCIX-to-PCIe) mode offers the Reverse Bridging capability, proven effective in bridging new PCI Express End Point Devices to legacy PCI Host CPUs with minimal impact to existing PCI Hardware/Software investment. Diodes' performance-tuned PCIe-to-PCI / PCIX /USB Bridges are specifically designed for a variety of applications and platforms: PC/Notebook systems, PCIe add-in cards, Compact PCI and PCIe systems, Multi-Function or Enterprise Printers, Network Routers and Switches, Industrial PC’s and Security/Video Surveillance Systems. As an active member and participant of PCI-SIG, PICMG, and ASI SIG Plugfest, all Diodes PCIe-to-PCI/PCIX Bridge Products are fully qualified on PCI-SIG Integrator’s list.
