Ultimate Renaissance has introduced a very low power, small footprint PCI-X to PCI-X bridge. The device is packaged in a 27mm x 27mm 380-pin BGA, and has power management features to minimise consumption. Extra, advanced features support a wide range of applications for all PCI-bus standards.
The PLX Technology PCI 6540 supports both transparent and true non-transparent operation, allowing a common module design to be used as a host or a peripheral in a system. Special features include FlowThru™ architecture, which delivers powerful buffer management and configuration to facilitate PCI-X-to-PCI bridging. Smart-Prefetch™ supports up to 2KB data prefetch with store and forward services to secondary bus PCI bus based processors. And Dynamic-Buffer-Management™ enhances PCI-X-to-PCI-X bridging. It is available in a 380-pin BGA package measuring 27mm x 27mm.
The PCI 6540 saves board space and power consumption, and supports PCI-X-to-PCI conversion, frequency conversions from a faster PCI-X to a slower PCI-X bus, address remapping, high availability hot swap, and universal system-to-system bridging.
Further features include 5V tolerance on I/Os and CompactPCI Hot Swap compliance, making the PCI 6540 suitable for high availability applications, including CPCI system slots or peripheral slots in telecom, Internet or networking applications. There are also 16 general purpose I/Os for driving LEDs or identifying module configuration, as well as a 10KB on-chip FIFO. Secondary clock outputs are also provided to drive other PCI components on the module. The device also supports up to eight bus masters.
The device is compliant with PCI 2.3 and PCI-X Rev 1.0a specifications, and supports all current PCI bus widths and speeds, including 32-bit, 33MHz; 64-bit, 66MHz; and the latest 64-bit, 133MHz PCI-X. This allows more devices to be attached to the widely-used PCI bus, enables intelligent adapters for PCI bus applications, and allows PCI buses of different speeds to become part of the same subsystem.
The PCI 6540 is available in the UK exclusively through Ultimate Renaissance, the sole distributor for the full PLX Technology product range.
