Tundra Semiconductor has announced the Tundra Tsi381 single lane PCI Express (PCIe) to PCI Bridge. Pin compatible with competing PCIe bridge products, this new product offers Tundra customers a superior solution with lower latency and better throughput than competitive offerings. The Tsi381 is ideal for applications that need to bridge from PCIe to PCI devices. Its flexibility, high performance, small footprint, and low power consumption make the Tsi381 ideal for numerous consumer and enterprise applications such as: line cards, network interface cards, motherboards, PC adapter cards and option cards, multi-function printers, media centers and digital video recorders.
Tundra entered the PCIe market in May, 2007 with the launch of the Tsi384, a four-lane PCI Express to PCI-X Bridge. “Tundra’s PCI product portfolio is further broadened today, with the launch of the Tsi381 PCI Express Bridge. Customers can now take advantage of another superior quality Tundra product that delivers product design excellence and reliable supply to enable their products to get to market ahead of the competition,” said Benny Chang , Tundra’s Chief Technology Officer. “The Tsi381 was designed by our Hyderabad, India and North American engineering teams to compete with and beat PCIe bridges currently in the market, on performance, latency and throughput. Customers that take advantage of this new product offering, receive Tundra’s world-class customer service and support,” continued Chang.
Compliant to the latest PCI Express Base 1.1 specification, the Tsi381’s x1 PCIe Interface enables the bridge to offer exceptional throughput of up to 2.5 Gbps. The device’s PCI Interface can operate up to 66 MHz and offers designers extensive flexibility by supporting three types of addressing modes: transparent, opaque, and non-transparent. Transparent mode operation is available for efficient, flow through configurations, while non-transparent bridging allows isolation between the Tsi381’s PCIe and PCI domains. Non-transparent bridging also enables multi-host systems and is used in applications such as intelligent adapter cards. Opaque mode provides semi-transparent operation for multi-processor configurations and enhanced private device support. The Tsi381 through its efficient architecture and deep buffering offers low latency and superior system performance. Its rich feature set provides designers with the ability to maximize performance for a wide range of PCI Express bridging applications.
