MUSILAND selects Tundra Semiconductor's PCI Express Bridge

Ottawa, Ontario - March 3, 2009 - Tundra Semiconductor Corporation (TSX: TUN), a leader in System Interconnect, announced that MUSILAND, China's well known computer sound card manufacturer has selected Tundra's PCI Express® (PCIe) Tsi382™ for the master card in its Sword II Analog-HD PCIe, X-Sword II Pro-HD PCIe, and X-Sword II Digital PCIe High Definition (HD) Audio System.

Tundra Semiconductor's Tsi382 is a high performance PCI Express to PCI bridge. The PCIe port of the Tsi382 supports a single lane configuration providing 2.5 Gbps throughput. The PCI port of the device can work at frequencies as high as 66 MHz and supports three types of addressing modes; transparent, opaque and non-transparent providing the designer with excellent flexibility. The Tsi382 has a highly efficient buffering mechanism and provides low latency and high throughput capacity. It also conforms to the following specifications:

•PCI Express base specification, version 1.1 •PCI Express PCI/PCI-X bridge specification, version 1.0 •PCI to PCI bridge architecture specification, version 1.2 •PCI partial bus specification, version 3.0 •PCI bus port power source management specification, version 1.2

The primary reason MUSILAND selected the Tsi382 as the PCI Express bridge for its X-SWORD II master card is its excellent performance, simple, low-risk design and impressive real time data transmission. Verification through actual testing shows that the Tsi382 offers the industry's lowest latency across the bridge so that the signal loss and distortion are negligible in this application.

The X-SWORD II system includes; hardware, software, including PCI, PCIe, and USB ports as well as nine master cards, seven daughter cards, three external boxes and a set of professional high definition audio drivers. This system supports almost all of the possible range of computer high fidelity music broadcasts, computer movie theaters, computer games, computer Karaoke, net chat, professional audio recording and professional digital output through free coordination of master card, daughter card and external box. This system also provides excellent performance and comprehensive functions. It can achieve 123dB 2-channel audio simulation output and 114dB 8-channel audio simulation output besides supporting all 24 Bit/192kHz broadcasting and recording. Regarding functionality, with the arrangement of MUSILAND's HD Saloon Driver, in addition to the full support of ASIO broadcasting and recording, Dolby Digital Live and Karaoke hardware processor, it can also perform audio frequency data decoding of Dolby hardware and DTS, digital signal de-bouncing and up-conversion, through the adoption of a DSP daughter card. In the future it will support HDMI output, with the release of a daughter card for second-generation audio frequency standards.
