TSB17BA1PW

Drivers, Receivers, Transceivers Overview

The TSB17BA1PW is a single-port 100-Mbps transceiver designed for IEEE Std 1394b signaling across unshielded twisted pair Category 5 (UTP5) cabling. It operates with a single 3.3-V supply or optional dual 3.3-V/1.8-V supplies and features power-down modes to conserve energy in battery-powered applications. The device provides one transceiver to drive IEEE Std 1394b signaling at 100 Megabits per second over up to 100 meters of UTP5 cable. It utilizes a low-cost high-performance 24-terminal TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Supports provisions of IEEE Std 1394b-2002 at S100B signaling rates
• Provides equalization to boost signal-to-noise ratio for data sensing
• Enables transmission and reception across up to 100 meters of UTP5 cable
• Includes power-down features to conserve energy in battery-powered applications

Drivers, Receivers, Transceivers Applications

• Transporting IEEE Std 1394b coded data across CAT5 or better cabling
• Connecting 1394b-capable ports on physical layers to UTP5 infrastructure
• Implementing 100-Mbits/s UTP5 connections using mechanical and magnetic infrastructure from 100baseT Ethernet designs

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the exact part number TSB17BA1PW, specifically confirming the PW terminal package designation. Ensure the datasheet revision aligns with the manufacturer's documentation standards. Confirm that the device meets RoHS compliance requirements as specified by Texas Instruments. Validate that the ordering suffix corresponds strictly to the package type without implying functional changes unless explicitly documented.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 1394b S100B signaling over standard UTP5 cabling. Ensure the connected PHY supports only 100 Mbits/s in 1394b-only mode for correct functionality. Verify that the design accommodates the required external crossover implementation since the device lacks autocrossover logic. Consider the thermal characteristics and PCB layout requirements for sensitive input signals to maintain performance.

Drivers, Receivers, Transceivers Part Context

The TSB17BA1 is part of Texas Instruments' interface integrated circuit portfolio, specifically targeting IEEE 1394b physical layer implementations. It serves as a bridge between 1394b PHY devices and standard UTP5 cabling, enabling compatibility with existing 100baseT Ethernet infrastructure. This allows designers to leverage established mechanical and magnetic components for FireWire 800 connections.
