Product details
Overview
TSB43DB42ZHCR from Texas Instruments is a 1394a-2000-compliant link-layer controller with integrated dual-port PHY, supporting 400/200/100 Mbps operation, IEC61883-1/2/4/6/7 audio/video streaming, and Motorola 68K-style 16-bit asynchronous CPU interface. It serves as the IEEE 1394 protocol engine in HDTV and set-top box systems for transport stream handling without DTLA encryption.
For engineers reviewing the TSB43DB42ZHCR datasheet, TSB43DB42ZHCR pinout, TSB43DB42ZHCR application, or TSB43DB42ZHCR equivalent, key selection criteria include its BGA-196 ZHC package, PCI/68K bus compatibility, absence of M6 cipher hardware, support for three high-speed data ports (two configurable parallel/serial, one serial-only), and dedicated I2S/SPDIF/60958 audio interfaces.
Technical Context
The TSB43DB42ZHCR implements full IEEE 1394-1995 and 1394a-2000 link-layer functionality with hardware-assisted Self-ID verification and bus management. Its integrated PHY supports auto-negotiated 100/200/400 Mbps signaling across two physical ports.
It provides three independent high-speed data interfaces: two configurable as parallel or serial (HSDI0/HSDI1), and one serial-only (HSDI2); plus dual audio paths - one 60958-compliant SPDIF port and one I2S-style DAC interface for two-channel PCM - with PID filtering (32 filters per HSDI port) and packet insertion capability.

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 |
|---|---|---|---|
| TSB43DA42ZHCR | Includes M6 baseline DTLA encryption/decryption hardware; adds secure key generation and up to three encrypted streams. | Required for MPEG2-DVB/DSS content protection compliance; not needed for non-encrypted AV distribution. | Select TSB43DA42ZHCR only if DTLA licensing and hardware-based encryption are mandatory for your content pipeline. |
| FW643 | Oxford Semiconductor FW643 offers PCI Express interface instead of PCI/68K; lacks IEC61883-7 (DSS) support and HSDI configurability. | Better suited for PC add-in cards than embedded consumer AV gear; no native SPDIF/I2S audio ports. | Choose FW643 for x86-based media PCs needing PCIe connectivity; avoid for resource-constrained STB/HDTV designs requiring integrated audio interfaces. |
Compared with TSB43DA42ZHCR, TSB43DB42ZHCR removes encryption logic to reduce cost and licensing burden while retaining identical link-layer, PHY, and IEC61883 streaming capabilities; FW643 diverges in host interface, audio integration, and standard coverage, making it unsuitable as a drop-in replacement.

FAQ
What is the primary function of the TSB43DB42ZHCR in an AV system?
The TSB43DB42ZHCR serves as a full IEEE 1394a-2000 link-layer controller with integrated dual-port PHY, handling isochronous and asynchronous packet processing for digital audio/video transport. In systems like HDTVs and STBs, the TSB43DB42ZHCR formats IEC61883-compliant streams, manages HSDI/SPDIF/I2S interfaces, and performs bus management - all without DTLA encryption hardware found in the TSB43DA42ZHCR variant.
Does the TSB43DB42ZHCR support PCI bus interfacing?
Yes, the TSB43DB42ZHCR supports PCI interface operation at 33 MHz and complies with PCI specification requirements when configured in PCI mode using the PCI_CLK and associated control signals. However, it operates exclusively as a PCI slave device and requires external DMA - the TSB43DB42ZHCR does not implement PCI bus mastering functionality.
How does the TSB43DB42ZHCR differ from the TSB43DA42ZHCR?
The TSB43DB42ZHCR is functionally identical to the TSB43DA42ZHCR except for the omission of DTLA-compliant M6 encryption/decryption hardware, secure key generation, and related firmware support. This makes the TSB43DB42ZHCR suitable for non-DRM applications where content protection is unnecessary, reducing licensing complexity and BOM cost while preserving all IEC61883 streaming, PHY, and interface capabilities.
What audio standards does the TSB43DB42ZHCR natively support?
The TSB43DB42ZHCR natively supports IEC61937 (SPDIF), IEC60958 (digital audio interface), and I2S-style two-channel PCM output for DAC interfacing. It also implements IEC61883-6 (audio/music) and IEC61883-7 (DSS) packet formatting for isochronous transport - all handled in hardware without CPU intervention during streaming.
Is the TSB43DB42ZHCR pin-compatible with other devices in the TSB43DA42/DB42 family?
Yes, the TSB43DB42ZHCR shares identical pinout, package dimensions (196-ball ZHC BGA), and electrical characteristics with TSB43DA42ZHCR and other ZHC-packaged variants in the family. This allows direct PCB footprint reuse across both encryption-enabled and non-encryption versions, simplifying design flexibility and inventory management for manufacturers targeting multiple content-protection tiers.
