TSB82AA2

The Texas Instruments TSB82AA2 is a discrete 1394b link-layer device, functioning as an OHCI-Lynx controller. It is engineered to meet demanding 1394b bus requirements, offering exceptional 800M bits/s performance for efficient data movement between PCI and 1394 buses.

Key electrical specifications include a single 3.3-V supply with an internal 1.8-V core voltage, and support for both 3.3-V and 5-V PCI signaling environments. The device features selectable 33-MHz/64-bit and 33-MHz/32-bit PCI interfaces. It supports serial bus data rates of 100M, 200M, 400M, and 800M bits/s. Deep FIFOs are integrated to tolerate large host latency, with asynchronous transmit and receive FIFOs at 5K and 2K respectively, and isochronous transmit and receive FIFOs at 2K each.

This controller also provides intelligent power management capabilities, supporting D0, D1, D2, and D3 power states. It includes features like physical write posting, a serial ROM or boot ROM interface for 2-wire serial EEPROM devices, and a multifunction terminal supporting PCI_CLKRUN protocol. Digital video and audio performance enhancements are also noted.

The TSB82AA2 is available in a 144-terminal LQFP (PGE) package or a 176-ball MicroStar BGA (GGW) package. It operates within a commercial temperature range of 0 to 70°C.
