The TSB14AA1A (TSB14AA1A refers to all three devices: TSB14AA1A, TSB14AA1AI, and TSB14AA1AT) is the second-generation 1394 backplane physical layer device. It is recommended for use in all new designs instead of the first generation TSB14C01A. It provides the physical layer functions needed to implement a single port node in a backplane based 1394 network. The TSB14AA1A provides two pins for transmitting, two for receiving, and two pins to externally control the transceivers for data and strobe. In addition to supporting open-collector drivers, the TSB14AA1A can also support 3-state† (high-impedance) drivers. The TSB14AA1A is not designed to drive the backplane directly; this function must be provided externally. The TSB14AA1A is designed to interface with a link-layer controller (LLC), such as the TSB12LV01B, TSB12LV32, TSB12LV21B, etc.
