OXPCIe200 PCIe-to-USB 2.0 bridge

PLX Technology Inc. has launched the PCIe-to-USB 2.0 host controller bridge tailored for a broad range of market applications including industrial control, PC peripherals, ExpressCard modules, point-of-sale terminals, servers, communications systems and embedded designs.

The OXPCIe200 is a unique device as it provides a single-chip solution for multiple-interface needs, thus replacing multichip solutions that add to the BOM cost, consume more power and require valuable board space. This advanced multiport PCIe bridge offers serial connectivity comprised of two USB 2.0 host ports, SPI or SRAM interface, a 950 UART port, GPIOs and Rx/Tx FIFOs. The highly integrated device also delivers up to 62.5Mbit/s data throughput while its advanced system management architecture substantially reduces CPU and system overhead. Other key features of the OXPCIe200 include a low power requirement of 300mW, a small footprint (9mm x 9mm) Thin Array Plastic Package (TAPP), and support for industrial temperature.

The OXPCIe200 uses operating system-native USB drivers and dedicated PLX device drivers that are quality-assured, exhaustively tested and Windows Hardware Quality Labs (WHQL)-approved. The device is PCI-SIG PCIe specification-complianthaving successfully completed the organization's comprehensive interoperability compliance testing proceduresand is listed on the group's approved Integrators List.

Empowering designers with time- and cost-saving tools, PLX's Oxide software development kit accelerates product development and time-to-market by enabling designers to customize serial connectivity devices such as the OXPCIe200 in minutes. Oxide requires no software expertise and offers an intuitive graphical user interface for simple point-and-click feature selection with sensible text box entry for fast, error-free customization without resorting to source-code editing. Making specific product customizations is a simple matter of checking boxes and filling out text in the Oxide GUI.

"PLX has extensive market experience with PCIe interconnects, and bridging to USB technology now opens new opportunities for designers to channel the high-speeds of multiple endpoints," said David Raun, VP of marketing and business development, PLX. "Our charter is to continue product leadership in PCIe Gen 1 and Gen 2 and USB 2.0, while at the same time applying that expertise to next-generation interconnects PCIe 3.0 and USB 3.0."

The OXPCIe200 is in full production today with volume prices at $7.65.
