The TSB82AA2 OHCI-Lynx is a discrete 1394b link-layer device from TI, which supports PCI burst transfers and deep FIFOs.
The TSB82AA2 is a 1394b OHCI‑Lynx link‑layer device that provides PCI burst transfers, deep FIFOs, and support for 100M‑800M bits/s serial bus data rates. It operates from a single 3.3 V supply with an internal 1.8 V core regulator and supports D0‑D3 power‑management states. The device offers selectable 33 MHz/64‑bit or 33 MHz/32‑bit PCI interfaces and includes features such as programmable transmit thresholds, isochronous receive enhancements, and hardware support for digital video and MPEG streams.
Packaging options include a 144‑terminal LQFP (PGE) and a 176‑ball MicroStar BGA (GGW) with RoHS‑compliant finishes. Mechanical drawings provide dimensions for both package types. The datasheet also contains compliance information, warranty notices, and important usage restrictions for safety‑critical, military, aerospace, and automotive applications.
