The Texas Instruments TSB82AF15-EP is a single-function PCI Express™ (PCIe) to PCI local bus translation bridge, where the PCI bus interface is internally connected to a 1394b open host controller/link-layer controller. When the TSB82AF15-EP is properly configured, this solution provides full PCIe to 1394 link layer controller.

The TSB82AF15-EP simultaneously supports up to four posted write transactions, four nonposted transactions, and four completion transactions pending in each direction at any time. Each posted write data queue and completion data queue can store up to 8K bytes of data. The non-posted data queues can store up to 128 bytes of data.
