TSB41BA3BPFPG4

Drivers, Receivers, Transceivers Overview

The TSB41BA3BPFPG4 is an IEEE 1394b three-port cable transceiver and arbiter manufactured by Texas Instruments. It provides the digital and analog transceiver functions required to implement a three-port node in a cable-based IEEE 1394 network. The device supports data rates up to 400 Mb/s and operates with dual power supplies of 1.85 V and 3.3 V. It features a propagation delay of 7 ns and draws 75 mA of operating supply current. The component is housed in an HTQFP-80 package and is rated for operation between -40°C and +105°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides integrated digital and analog transceiver functions for three-port IEEE 1394 nodes
• Supports high-speed data transmission at 400 Mb/s
• Includes arbitration logic for bus management
• Operates on dual voltage rails of 1.85 V and 3.3 V

Drivers, Receivers, Transceivers Applications

• Implementation of three-port nodes in cable-based IEEE 1394 networks
• Digital interface circuits requiring 1394 connectivity
• Industrial equipment utilizing IEEE 1394b standards

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PPG4 against official Texas Instruments documentation to confirm lead-free status and RoHS compliance. Confirm the package type is HTQFP-80. Check for end-of-life status as similar variants are marked obsolete. Ensure moisture sensitivity levels are addressed during storage and handling.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing a three-port IEEE 1394b node requiring both arbitration and transceiver capabilities. Compare against the TSB41AB3 series if only IEEE 1394a support is needed. Verify that the 400 Mb/s speed meets system requirements, as higher speeds require different controllers. Ensure the HTQFP-80 footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TSB41BA3A/B family of IEEE 1394b transceivers. It serves as a bridge between the host controller and the physical cable medium. Similar parts include the TSB41BA3B and TSB41BA3ATPFPEP. These devices are critical for maintaining signal integrity and managing bus traffic in legacy high-performance serial interfaces.
