TSB43AA22PDT

Controllers Overview

The TSB43AA22PDT is an IEEE 1394 physical layer controller manufactured by Texas Instruments. It supports the IEEE 1394-1995 and 1394a-2000 standards, enabling high-speed serial communication for FireWire applications. The device integrates a PCI interface for host connectivity and operates with a supply voltage of 3V to 3.6V. Packaged in a 128-TQFP (14x14 mm) format, it is designed for robust data transfer in peripheral interconnect systems.

Controllers Feature Summary

• Supports IEEE 1394-1995 and 1394a-2000 protocols for FireWire compatibility
• Integrates PCI bus interface for direct host system connection
• Operates within a standard 3V to 3.6V power supply range

Controllers Applications

• FireWire peripheral interconnect controllers
• High-speed digital camera interfaces
• External storage device controllers

Controllers Procurement Notes

Verify component authenticity through authorized channels due to potential availability from secondary markets. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any specific handling or soldering requirements relevant to the 128-TQFP form factor.

Controllers Selection Notes

Select this component when designing systems requiring strict compliance with legacy IEEE 1394 standards. Ensure the PCB layout accommodates the 128-pin TQFP footprint. Verify that the host system provides the necessary PCI signaling levels and timing constraints for reliable operation.

Controllers Part Context

This part belongs to the TSB43 series of IEEE 1394 PHY controllers. It serves as a bridge between PCI-based hosts and FireWire peripherals. The 'AA' suffix typically denotes specific feature sets or speed capabilities within the family, distinct from variants like the AB21 or AB23.

Controllers Replacement Considerations

Direct substitutes include the TSB43AB21AIPDT and TSB43AB23PDTG4. These components share the same 128-TQFP package and core IEEE 1394 functionality. Verify pin-to-pin compatibility and electrical specifications before swapping.
