TSB43AB23PGE

Controllers Overview

The Texas Instruments TSB43AB23PGE is an integrated IEEE 1394a-2000 OHCI PHY/link-layer controller (LLC) compliant with the PCI Local Bus Specification and PCI Power Management Interface. It transfers data between a 33-MHz PCI bus and the 1394 bus at speeds of 100M, 200M, and 400M bits/s. The device provides three 1394 ports with separate cable bias (TPBIAS). It supports D0, D1, D2, and D3 power states and utilizes deep FIFOs to buffer 1394 data against PCI latency. An external 24.576-MHz crystal or clock serves as the reference for the cable ports.

Controllers Feature Summary

• Supports hardware enhancements for digital video (DV) and MPEG data stream reception and transmission
• Provides physical write posting buffers and highly-tuned physical data path for SBP-2 performance
• Includes multiple isochronous contexts and advanced internal arbitration

Controllers Applications

• PCI-based host controllers requiring IEEE 1394 connectivity
• Battery-operated applications utilizing IEEE 1394a-2000 power-down features
• Digital video (DV) and MPEG data stream processing systems

Controllers Procurement Notes

Verify the specific package type and suffix against official documentation before procurement. Confirm that the component meets all required electrical characteristics and operating temperature ranges for the intended application environment. Ensure compatibility with the target system's PCI interface specifications.

Controllers Selection Notes

Select this component when a fully compliant OHCI PHY/link-layer controller is required for PCI-based designs. Consider the need for three independent 1394 ports with separate cable bias. Evaluate the requirement for low-power operation in battery-powered devices and the necessity for DV/MPEG timestamp enhancements.

Controllers Part Context

The TSB43AB23 is part of Texas Instruments' 1394 Host Controller Solutions family. It integrates both the link-layer controller and the physical layer transceiver functions into a single CMOS device. This integration simplifies the design of high-performance serial bus nodes by reducing the number of external components required.
