PCIe/PCI 桥接器

Diodes 提供各种PCIe桥接产品，正向(PCIe-to-PCI/PCIX)桥接器为Root端的 PCI Express和Device端的PCI/PCIX提供有效的完整桥接解决方案。反向(PCI/PCIX-to-PCIe) 桥接器可连接新的PCI Express Device到旧的 PCI Host CPU，对现有 PCI 硬件 / 软件变动非常小。

通过Diodes PCIe桥接器，设计者可以将PCI、PCIX、USB接口连接到串行PCI Express 架构，广泛应用在个人 / 笔记本电脑系统、PCIe 附加卡、CompactPCI 和 PCIe 系统、多功能或商用打印机、网络路由器和交换机、工业计算机，以及安全 / 影像监控系统。Diodes 为 PCI-SIG、PICMG 及 ASI SIG Plugfest 积极参予的会员，所有 PCIe-to-PCI/PCIX 网桥产品皆通过测试，名列 PCI-SIG 合格名单。

PCIe / PCI Bridges Details

Pericom offers the following bridge solutions:

PCI to PCI
PCI-X to PCI-X
PCIe to PCI
PCIe to PCI-X
PCIe to UART I/O Bridge

Bridge Benefits and Features

PCI & PCI-X Bridges allow add-on devices in a system
Creates a separate secondary bus
Permits more devices or “loads” to be added to the system
- Allows for more slots for adapter cards in a system
- Allows for multiple devices on a line card or add-in card

Intel Compatible PCI-to-PCI Bridges
