TSB43AB22APDT

Controllers Overview

The TSB43AB22APDT is an IEEE 1394 physical layer controller manufactured by Texas Instruments. It supports the IEEE 1394-1995 and 1394a-2000 standards, as well as OHCI specifications. The device features a PCI interface for host connectivity and operates on a 3.3V supply voltage. It is housed in a 128-TQFP package with dimensions of 14x14 mm. The component complies with RoHS3 regulations and has a Moisture Sensitivity Level (MSL) of 3 (168 hours).

Controllers Feature Summary

• Supports IEEE 1394-1995 and 1394a-2000 protocols including Firewire and i.Link.
• Integrates a PCI interface for system connectivity.
• Functions as a dedicated physical layer controller.

Controllers Applications

• PCI-based computer systems requiring IEEE 1394 connectivity.
• Peripheral devices utilizing Firewire or i.Link interfaces.
• Hardware implementing Open Host Controller Interface (OHCI) standards.

Controllers Procurement Notes

Verify the specific suffix 'AIPDT' against official documentation to confirm package and temperature range details. Confirm current availability status as this series may be discontinued. Ensure compatibility with existing 3.3V power designs and 128-TQFP footprint requirements before procurement.

Controllers Selection Notes

Select this component when a PCI-hosted IEEE 1394 physical layer solution is required. Compare against similar models like the TSB43AB21AIPDT or TSB43AB23PDTG4 for pinout and feature differences. Verify that the 128-TQFP package size fits the target PCB layout constraints.

Controllers Part Context

This part belongs to the TSB43 family of IEEE 1394 controllers from Texas Instruments. These components are designed to handle the physical layer signaling for high-speed serial data transmission. The family includes variants supporting different packaging options and operating temperatures.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers for the TSB43AB22APDT were not identified in available sources. Evaluate the TSB43AB21AIPDT or TSB43AB23PDTG4 for potential functional equivalence, subject to rigorous electrical and mechanical verification.
