IDT expands industry-leading PCI Express portfolio with PCIe-to-PCI bridge

SAN JOSE, USA: IDT (Integrated Device Technology Inc.) has announced a PCI Express (PCIe)-to-PCI bridge tailored for the computing and consumer markets.

The low power consumption and innovative features — such as its advanced buffering and queuing techniques — offered by the IDT bridge help designers improve overall system efficiency, making this device ideal for PC motherboards, PC adapter cards, multi-function printers, mobile applications and digital video recorder (DVR) cards.

The new IDT bridge provides a smooth transition from legacy PCI to PCIe as applications migrate to the newer standard. Moreover, the bridge features an impressive 40-percent reduction in power consumption from alternative solutions — the lowest power consumption available in the industry.

“This third-generation bridge leverages the performance characteristics of its predecessors while incorporating new techniques in power reduction to provide the most competitive consumer PCIe-to-PCI bridge in the industry.”

The IDT PEB383 bridge has been designed to help IDT customers simplify board layout and manufacturability. The IDT PCIe-to-PCI bridge is tailored to match design characteristics of leading consumer processors, such as Intel and AMD, helping ensure ease of integration. In addition, the new PCIe-to-PCI bridge features the lowest latency and highest bandwidth compared to alternative solutions, resulting in the highest-quality overall system solution.

The IDT PEB383 also features advanced buffering and queuing techniques, including short-term caching (STC), which provides more than a 500-percent improvement with non-posted transactions, helping improve overall system performance.

“PCI Express has been fully adopted and is growing within the consumer market segment,” says Steve Peterson, Director of Intel Chipset Marketing. “For consumer designs that still require legacy PCI, the IDT PEB383 provides a smooth transition as add-in cards complete the transition from legacy PCI to PCI Express.”

The IDT PEB383 bridge features a PCIe port that provides 2.5Gbps throughput in a single lane configuration. This PCI port is a 32-bit-wide interface supporting frequencies up to 66MHz, allowing legacy devices to interface with the PCIe hierarchy. The PCI interface also offers a comprehensive feature set and 5V I/O tolerance to ensure interoperability with the earliest of PCI I/O devices, providing IDT customers with increased design flexibility.

“With the PEB383 bridge, our customers can expect complete interoperability from the PCIe interface to their existing PCI solutions,” said Mario Montana, vice president and general manger for the IDT Enterprise Computing Division. “This third-generation bridge leverages the performance characteristics of its predecessors while incorporating new techniques in power reduction to provide the most competitive consumer PCIe-to-PCI bridge in the industry.”

The new PEB383 bridge is priced at $4.95 for 10,000 units and is available in a 14x14 millimeter 128-pin Quad Flat Pack (QFP) and a small 10x10mm 132-pin Quad Flat No-Lead (QFN) package.
