Product details
Overview
TSB43DA42AZHCR from Texas Instruments is a 1394a-2000-compliant IEEE 1394 link-layer controller with integrated dual-port PHY, supporting 100/200/400 Mbps operation, M6 DTLA encryption/decryption for up to three MPEG2 or audio transport streams, and IEC61883-1/2/4/6/7-compliant audio/video packet formatting. It serves as the core 1394 interface in HDTV and set-top box systems handling encrypted transport stream bridging.
For engineers reviewing the TSB43DA42AZHCR datasheet, TSB43DA42AZHCR pinout, TSB43DA42AZHCR application, or TSB43DA42AZHCR equivalent, key selection criteria include M6 cipher hardware acceleration, dual HSDI port configuration (one serial-only), SPDIF/I2S audio interface support, and BGA-196 ZHC package compatibility with consumer electronics thermal and layout constraints.
Technical Context
The TSB43DA42AZHCR implements a full IEEE 1394a-2000 link layer with bus management, self-ID verification, and asynchronous DMA-capable 16-bit Motorola 68K-style interface. Its integrated PHY complies with IEEE 1394-1995 and supports all three legacy speeds (100/200/400 Mbps) across two physical ports.
Hardware-accelerated DTLA encryption uses M6 baseline per 5C specification, enabling concurrent encryption/decryption of three MPEG2-TS or audio streams with full AKE assistance and secure ex-CPU loading of keys. PID filtering (32 filters per HSDI port) and packet insertion buffers (for DAT/PMT/SIT/DIT) are implemented on-die.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standard Compliance | IEEE 1394-1995 and IEEE 1394a-2000 - ensures interoperability with legacy and enhanced FireWire devices including bus arbitration and cycle master functions. |
| Data Rates | 100/200/400 Mbps - selectable PHY speed matching source sink capabilities without protocol translation or external rate adaptation. |
| Encryption Capability | M6 DTLA baseline (TSB43DA42 only) - enables hardware-accelerated encryption/decryption of up to three simultaneous MPEG2 or audio transport streams per 5C spec. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar IEEE 1394 link-layer controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB43DB42AZHCR | Identical pinout and interface but lacks M6 DTLA encryption/decryption hardware and associated key management logic. | Supports unencrypted 1394 A/V bridging only; cannot process MPEG2-TS with DTLA protection or perform hardware AKE. | Select when content security is not required and DTLA licensing must be avoided. |
| FWF010-196 | Single-port 1394a PHY-only device (no link layer); requires external link controller and separate encryption IP. | Demands full external implementation of IEC61883 formatting, bus management, and M6 cipher - significantly higher BOM and firmware effort. | Select only for highly customized PHY-layer extensions where full link-layer integration is undesirable. |
Compared with TSB43DB42AZHCR, the TSB43DA42AZHCR adds mandatory DTLA compliance for broadcast content; compared with FWF010-196, it integrates link-layer logic, encryption, and IEC61883 offload - reducing total system gate count and firmware complexity by >70%.

FAQ
What is the primary function of the TSB43DA42AZHCR in a consumer electronics system?
The TSB43DA42AZHCR serves as a fully integrated IEEE 1394a-2000 link-layer controller with dual-port PHY and hardware M6 DTLA encryption. In systems like HDTVs and STBs, the TSB43DA42AZHCR receives encrypted MPEG2 transport streams, decrypts them using on-chip cipher logic, formats packets per IEC61883 standards, and delivers audio/video data via HSDI or SPDIF interfaces - eliminating need for external crypto or protocol engines.
Does the TSB43DA42AZHCR support both PCI and Motorola 68K host interfaces?
No - the TSB43DA42AZHCR supports only the 16-bit Motorola 68K-style asynchronous interface with external DMA capability; it does not implement a PCI interface. While the datasheet notes PCI compliance for the TSB43DA42/DB42 family, that applies to earlier variants (e.g., TSB43DA42AGHC). The TSB43DA42AZHCR variant uses the 68K bus exclusively, as confirmed by its pinout and ordering information.
What audio interface standards does the TSB43DA42AZHCR natively support?
The TSB43DA42AZHCR natively supports IEC61937 (S/PDIF) for compressed audio transport and IEC61883-6 (audio/music) for uncompressed PCM streams via its I2S-style DAC interface. It handles two-channel PCM output directly, with dedicated WS/BCLK/MCLK signals, and performs real-time M6 encryption on SPDIF input before 1394 transmission - all without host CPU involvement.
How many simultaneous encrypted streams can the TSB43DA42AZHCR process?
The TSB43DA42AZHCR supports up to three simultaneous encrypted or decrypted MPEG2 or audio transport streams using its hardware M6 cipher engine, as specified in the 5C DTLA baseline implementation. This capability is exclusive to the TSB43DA42 series; the TSB43DB42 variant omits this feature entirely.
Is the TSB43DA42AZHCR pin-compatible with other members of the TSB43DA42 family?
Yes - the TSB43DA42AZHCR shares identical pinout and package (196-pin ZHC BGA) with TSB43DA42GHC, TSB43DA42AGHC, and TSB43DB42AZHC, enabling drop-in replacement within the same footprint. All ZHC-package variants use the same MICROSTAR BGA drawing, same pad layout, and same thermal/mechanical specifications per TI's packaging addendum.
