TSB81BA3PFPG4

Drivers, Receivers, Transceivers Overview

The TSB81BA3PFPG4 is an IEEE P1394b Three-Port Cable Transceiver Arbiter manufactured by Texas Instruments. It is housed in an 80-pin HTQFP package with an operating temperature range of 0 to 70 degrees Celsius. The device features differential outputs and six driver bits, functioning as a line transceiver interface integrated circuit. It contains three functional units within the single component.

Drivers, Receivers, Transceivers Feature Summary

• Supports IEEE 1394b standard for high-speed serial bus communication
• Integrates cable transceiver and arbiter functions for multi-port connectivity
• Provides differential output signaling for reliable data transmission

Drivers, Receivers, Transceivers Applications

• IEEE 1394b physical layer implementation in computing nodes
• Multi-port firewire hub or bridge designs
• Digital video and audio equipment requiring high-speed serial interconnects

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with lead-free and RoHS standards. Confirm the HTQFP-80 package type matches the target PCB footprint. Ensure the external clock circuit provides the required 98.3040 MHz input signal for proper PHY operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing an IEEE 1394b compliant node requiring three ports. Unlike the TSB41BA3 series which accepts 49.1520 MHz clocks, this device requires an external clock of 98.3040 MHz. Verify that the system clock jitter characteristics meet the strict requirements for correct PHY functioning.

Drivers, Receivers, Transceivers Part Context

This component belongs to the Texas Instruments TSB81BA3 family of IEEE 1394b physical layer devices. It serves as a specialized interface solution for implementing the FireWire standard in consumer electronics and industrial applications requiring robust serial data transfer capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

The TSB81BA3D and TSB81BA3DI are functionally equivalent parts within the same family. Verify pin compatibility and package dimensions before substitution.
