Texas Instruments TSB82AA2IPGEEP

Overview

TSB82AA2IPGEEP from Texas Instruments is a discrete IEEE 1394b OHCI-Lynx link-layer controller IC that bridges 33-MHz PCI (32-/64-bit) and 1394b PHY-layer devices. It supports S100/S200/S400/S800 serial data rates up to 800 Mbits/s, delivers 264 MB/s peak PCI throughput in 64-bit mode, and implements deep FIFOs (5K async TX, 2K iso TX/RX) for latency-tolerant isochronous streaming in digital video and storage applications.

For engineers reviewing the TSB82AA2IPGEEP datasheet, TSB82AA2IPGEEP pinout, TSB82AA2IPGEEP application, or TSB82AA2IPGEEP equivalent, this page provides verified technical context, pin-level circuit roles, real-world use cases in DV/MPEG transport and RAID/SAN peripherals, and validated alternative controllers with documented functional and power-state differences.

Technical Context

The TSB82AA2IPGEEP implements the IEEE 1394b link layer per OHCI v1.2 and supports full PCI 2.3 compliance including D0–D3hot/cold states, PME wake events, and memory-mapped non-prefetchable register access. Its architecture integrates dual isochronous contexts, hardware CIP header stripping for received DV streams, and automatic timestamp insertion for transmitted MPEG/DV packets per IEC 61883-1.

It features a 1.8-V internal core supplied by an integrated 3.3-V-to-1.8-V regulator, enabling ultra-low power operation across extended temperature (–40°C to +85°C). The device interfaces directly with TI's TSB81BA3 PHY via 8-bit parallel PHY-Link signals and supports 2-wire serial EEPROM boot configuration.

FAQ

What is the maximum serial bus data rate supported by the TSB82AA2IPGEEP?

The TSB82AA2IPGEEP supports IEEE 1394b serial bus data rates up to 800 Mbits/s (S800), fully backward compatible with S100, S200, and S400 modes. This capability is implemented in hardware and requires pairing with an S800-capable PHY such as the TSB81BA3. The TSB82AA2IPGEEP achieves sustained throughput by leveraging deep FIFOs and optimized physical data paths - confirmed in Section 1.1 of the SCPS167A datasheet.

Does the TSB82AA2IPGEEP support PCI 64-bit operation?

Yes, the TSB82AA2IPGEEP supports both 32-bit and 64-bit PCI configurations at 33 MHz. In 64-bit mode, it achieves up to 264 MB/s peak transfer rate when connected to a compliant memory controller. Configuration is determined by hardware strapping and register settings per Section 2.1 and Table 2–5 in the SCPS167A datasheet. The device automatically detects bus width during enumeration.

How does the TSB82AA2IPGEEP handle digital video (DV) timing compliance per IEC 61883-1?

The TSB82AA2IPGEEP implements hardware-level IEC 61883-1 support including automatic CIP header stripping on isochronous receive and precise synchronization timestamp insertion on transmit. These functions are controlled via the Isochronous Receive Digital Video Enhancements Register (TI extension offset A80h) and ensure sub-cycle-timer accuracy for DV/MPEG streams - detailed in Sections 1.1 and 5.4 of SCPS167A.

What power management states does the TSB82AA2IPGEEP support?

The TSB82AA2IPGEEP fully supports PCI-defined D0, D1, D2, and D3hot/cold power states per the PCI Bus Power Management Interface Specification and PC 2001 Design Guide. It generates PME wake events and uses an integrated 3.3-V-to-1.8-V regulator to minimize active and standby current - enabling ultra-low power operation across –40°C to +85°C, as specified in Sections 1.1 and 1.2 of SCPS167A.

Is external EEPROM required for TSB82AA2IPGEEP operation?

An external 2-wire serial EEPROM is optional but recommended for reliable plug-and-play operation. It stores the node ID, configuration ROM, and vendor-specific parameters loaded at power-up via the SCL/SDA pins. Without EEPROM, default values apply, but system enumeration may fail or produce non-unique node IDs - per Section 7 and Table 7–1 in SCPS167A.
