TSB43AB23 Description

Short technical summary and product information.

The Texas Instruments TSB43AB23 is an OHCI 1.1 compliant IEEE 1394a link layer controller. It integrates a 400-Mbps, 3-port PHY, providing a high-performance serial bus solution. This controller is fully compliant with IEEE Std 1394-1995 and IEEE Std 1394a-2000, ensuring interoperability with FireWire and i.LINK implementations.

 

Key features include support for connection debounce, arbitrated short reset, multispeed concatenation, and arbitration acceleration. It operates with a 1.8-V core logic and supports universal PCI interfaces compatible with 3.3-V and 5-V signaling. The device is housed in a 144-pin LQFP package measuring 22 mm x 22 mm.

 

Designed for power efficiency, the TSB43AB23 includes power-down features such as automatic device power down during suspend and PCI power management. It also offers an ultralow-power sleep mode. The controller utilizes a low-cost 24.576-MHz crystal for data transmission and reception at 100M bits/s, 200M bits/s, and 400M bits/s.
