Introduction
1.1
Product Overview The BRG1825 is designed to provide a PCI to PCI Express (PCIe) Bridge. It allows for the expansion of existing PCI based systems with the latest PCI Express devices, such as high-speed analog I/O, USB 3.0, and video controllers. Up to six PCIe/104 modules may be added from a single PCI-104 slot position without requiring any modifications to software. It is compatible with all PCI cpuModules.
1.2
Board Features
PCI Upstream Interface to CPU PCI Express (PCIe) Downstream Interface to Peripheral Cards Power rails (+5V, +3.3V, +12V) connected between the PCIe and PCI bus PCI Bus: o 32-bit, 33 MHz PCI Bus o PCI Target Controller allows PCI access to PCI Express Target Devices o PCI Master Controller allows full transparent access to PCI resources o Message Signaled Interrupt (MSI) support o Legacy Interrupt support o 5V or 3.3V signal level PCI Express Bus: o Provides four x1 links o Provides a single lane to each of the two x4 links or x16 link o Provides 2.5 Gbps in each direction o Single lane and single Virtual Channel operation Compatible with multi-Virtual Channel chipsets o Packetized serial traffic with PCI Express Split Completion protocol o Data Link Layer Cyclic Redundancy Check (CRC) generator and checker o Automatic Retry of bad packets o In-band interrupts and messages o Message Signaled Interrupt (MSI) support o Supports peer-to-peer transactions o Total throughput to the CPU is limited by the PCI bus bandwidth
