Product details
Overview
TSB82AA2PGE from Texas Instruments is a discrete IEEE 1394b OHCI-Lynx link-layer controller that bridges 33-MHz PCI (32-/64-bit) and 1394b PHY devices. It supports S100/S200/S400/S800 serial data rates (up to 786.432 Mbits/s), features 5K asynchronous + 2K isochronous transmit FIFOs, 2K asynchronous + 2K isochronous receive FIFOs, D0–D3 power states with PME, and operates from a single 3.3-V supply with internal 1.8-V core regulation.
For engineers reviewing the TSB82AA2PGE datasheet, TSB82AA2PGE pinout, TSB82AA2PGE application, or TSB82AA2PGE equivalent, key selection considerations include S800 throughput capability, deep dual-mode FIFO buffering for sustained isochronous payloads, PCI power management compliance (PCI Bus Power Management Interface Specification), TI's 1394b PHY interface compatibility (e.g., TSB81BA3), and LQFP-144 packaging for legacy PC add-in card designs.
Technical Context
The TSB82AA2PGE implements a memory-mapped OHCI-compliant register set per IEEE Std 1394a–2000 and supports IEEE Draft Std 1394b. Its physical write posting buffers up to three outstanding transactions, and it enables out-of-order pipelining for asynchronous transmit requests to reduce latency impact.
It integrates hardware enhancements for digital video, including automatic CIP timestamp insertion on transmit and CIP header stripping on receive (via TI extension register A80h), and supports IEC 61883-1:1998-compliant DV/MPEG stream handling with synchronization timestamp modification logic to prevent stale values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Serial bus data rates | S100/S200/S400/S800 (98.304/196.608/393.216/786.432 Mbits/s) - enables full backward compatibility and high-bandwidth media transfer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1394b link-layer controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB82AA2GGW | BGA-176 package (MicroStar BGA), identical electrical specs and register set | Targeted for space-constrained embedded or mobile platforms requiring smaller footprint and better thermal dissipation | Select TSB82AA2GGW when board area is constrained and BGA assembly capability exists; not pin-compatible with TSB82AA2PGE |
| TSB82AA2-EP | Enhanced Product variant qualified for extended temperature (–55°C to 125°C) and higher reliability per defense/aerospace requirements | Used in ruggedized industrial, avionics, or medical systems where extended temp and radiation tolerance are mandatory | Choose TSB82AA2-EP only when MIL-STD-883 or AEC-Q200-level qualification is required; otherwise, standard TSB82AA2PGE suffices |
Compared with TSB82AA2GGW and TSB82AA2-EP, the TSB82AA2PGE offers optimal cost and manufacturability for commercial desktop PC add-in cards, leveraging LQFP-144 for ease of inspection, rework, and thermal management-while retaining identical link-layer functionality, S800 throughput, and OHCI-Lynx compliance.

FAQ
What is the maximum serial data rate supported by the TSB82AA2PGE?
The TSB82AA2PGE supports IEEE 1394b serial data rates up to S800 (786.432 Mbits/s), fully backward compatible with S100, S200, and S400 modes. This is achieved through its physical layer interface to companion PHY devices like the TSB81BA3, and confirmed in TI's SLLA221 datasheet. The TSB82AA2PGE maintains full OHCI-Lynx compliance across all four speeds without firmware or configuration changes.
Does the TSB82AA2PGE require an external 1.8-V supply?
No, the TSB82AA2PGE does not require an external 1.8-V supply. It integrates an improved 3.3-V-to-1.8-V voltage regulator that powers the internal core logic. Only a single 3.3-V supply is needed, simplifying power design and reducing bill-of-materials count. This feature is explicitly documented in the TSB82AA2PGE datasheet section on power requirements and confirmed in the "Single 3.3-V supply (1.8-V internal core voltage with regulator)" feature list.
Is the TSB82AA2PGE pin-compatible with other members of the TSB82AA2 family?
No, the TSB82AA2PGE is not pin-compatible with the TSB82AA2GGW (BGA-176) due to differing package types and pin counts. While both share identical electrical functionality and register mapping, the LQFP-144 (PGE) and MicroStar BGA-176 (GGW) packages have entirely different footprints and signal assignments. Pin compatibility exists only within the same package variant; cross-package substitution requires PCB redesign.
What power management states does the TSB82AA2PGE support?
The TSB82AA2PGE supports D0, D1, D2, and D3hot/cold power states per the PCI Bus Power Management Interface Specification, with PME (Power Management Event) wake capability. These states enable OS-directed power gating and wake-on-1394-event functionality. Support is hardware-implemented and verified in TI's SLLA221 datasheet, and requires appropriate BIOS and driver support to activate fully.
Can the TSB82AA2PGE be used without a companion 1394b PHY device?
No, the TSB82AA2PGE cannot operate standalone as a complete 1394b interface. It is a link-layer controller only and requires an external PHY-layer device (e.g., TSB81BA3) to handle physical signaling, cable arbitration, and differential pair drivers/receivers. The TSB82AA2PGE communicates with the PHY via an 8-bit parallel interface (PHY_DATA[7:0]), and no integrated PHY is present on-die.
