Tsi381 PCIe to PCI Bridge Product Brief Features Device Overview The IDT Tsi381 is a high-performance bus bridge that connects the General PCI Express protocol to the PCI bus standard. The Tsi381s PCIe Inter- PCI Express to PCI bridge face supports a x1 lane PCIe configuration, which enables the bridge to Transparent, Non-transparent, and Opaque modes offer exceptional throughput performance of up to 2.5 Gbps per transmit Efficient queuing and buffering for low latency and high and receive direction. throughput The devices PCI Interface can operate up to 66 MHz. This interface Compliant with the following specifications: offers designers extensive flexibility by supporting three types of PCI Express Base 1.1 addressing modes: transparent, opaque, and non-transparent.

Its package is designed to Packaging: simplify board layout for high reliability and signal integrity. A compre- 13x13 mm, 144-pin PBGA (10x10 mm option is available part hensive suite of design support resources are also available to aid number Tsi382) designers. Pinout and footprint compatible with PLX PEX 8111/8112 Pin compatibility with the PLX PEX8111 and PEX8112 make it easy Industrial temperature operating range for designers to migrate current designs to the Tsi381, and thereby bring RoHS-compliant package available them to market quickly and with low risk. 1 of 2 August 14, 2009 2008 Integrated Device Technology, Inc.Tsi381 Evaluation Board Product Brief High Performance In addition to low-latency operation and high throughput, the Tsi381 incorporates performance enhancing features, such as short-term caching, that can provide a significant performance boost in many appli- cations. Transparent, Non-transparent, and Opaque Bridging Transparent mode operation is available for efficient, flow through configurations, while non-transparent bridging allows isolation between the Tsi381s PCIe and PCI domains. Non-transparent bridging also enables multi-host systems and is used in applications such as intelli- gent adapter cards. Opaque mode provides semi-transparent operation for multi-processor configurations and enhanced private device support. Typical Applications The Tsi381 is suited to applications that need to bridge PCIe to downstream PCI devices. Its flexibility, high performance, small foot- print, and low power consumption, make it ideal for a wide range of applications, including: Digital video recorders Motherboards (server, SBC, industrial PC) PC adapter cards (communications, graphics, imaging, and multimedia) Multifunction printers Line cards and NICs Camera Camera Camera Camera Video Video Video Video Decoder Decoder Decoder Decoder PCI Bus Tsi381 80E2000 TA002 01 x1 PCIe Figure 2 PC Digital Video Recorder Card Application August 16, 2004August 16, 200 NOT AN OFFER FOR SALE The information presented herein is subject to a Non-Disclosure Agreement and is for planning purposes only.
