The TSB12LV23, also known as the PCI-Lynx, is a dedicated integrated circuit designed by Texas Instruments to serve as a PCI-to-1394 Host Controller. This advanced semiconductor device is specifically engineered to bridge the gap between the high-speed IEEE 1394 serial bus and the ubiquitous PCI local bus, commonly found in desktop computers and servers.

Key Features

• High-Speed Data Transfer: The TSB12LV23 supports 100Mbits/s, 200Mbits/s, and 400Mbits/s transfer rates, making it suitable for applications requiring fast data exchange such as video capture, storage systems, and multimedia devices.
• Compliance: Fully compliant with the PCI Local Bus Specification, Revision 2.1, and with the 1394-1995 Standard for a High Performance Serial Bus, it ensures compatibility with a wide range of systems and devices.
• Efficient Bus Utilization: The device employs an isochronous and asynchronous data transfer mechanism, which enhances bus utilization and ensures time-critical data is given priority.
• Integrated PHY: The inclusion of an integrated 1394a-2000 PHY allows for direct connection to the 1394 bus, simplifying design and reducing external component count.
• Flexible Configuration: The TSB12LV23 can be configured as a bus master or slave, providing flexibility in system design and integration.
