Product details
Overview
TSB12LV21BIPGF from Texas Instruments is an IEEE 1394-1995 Link Layer Controller (LLC) IC for high-speed serial bus interface design. It integrates a 32-bit CRC generator/checker, supports 100/200/400 Mb/s transfer rates, provides five scatter-gather DMA channels, and features 4 KB configurable FIFO RAM - enabling plug-and-play 1394 connectivity between PCI bus, PHY-link, and local bus peripherals in digital video and industrial data acquisition systems.
For engineers reviewing the TSB12LV21BIPGF datasheet, TSB12LV21BIPGF pinout, TSB12LV21BIPGF application, or TSB12LV21BIPGF equivalent, key selection considerations include its PCI Local Bus Specification Rev. 2.1 compliance, 3.3-V core with 5-V tolerant inputs, distributed DMA support across 1394 and local bus domains, and industrial-grade temperature range (–40°C to 85°C) as indicated by the 'I' suffix.
Technical Context
The TSB12LV21BIPGF implements full IEEE 1394-1995 link layer control including cycle master functionality, CSR architecture compliance per IEEE 1212-1991, and hardware-accelerated packet framing with 32-bit CRC generation and verification. Its dual-mode PCI interface operates as both bus master (for DMA) and slave (for register access), supporting 32-bit burst transfers at up to 33 MHz.
Local bus integration includes dedicated ZV (Zoomed Video) port for direct 1394 camera packet ingestion, plus RAM/ROM/AUX/ZV/GPIO ports mapped into PCI address space. Internal DMA uses packet control list (PCL) structures stored in PCI or local memory, enabling CPU-offload transfers with conditional branching, linking, and big/little-endian data handling without byte-swapping.

FAQ
What is the operating temperature range specified for the TSB12LV21BIPGF?
The TSB12LV21BIPGF is characterized for operation from –40°C to +85°C, qualifying it for industrial environments. This range is explicitly defined in the TI datasheet SLLA213 and distinguishes it from the commercial-grade TSB12LV21BPGF (0°C to 70°C) and military-grade TSB12LV21BM (–55°C to 125°C). The 'I' in TSB12LV21BIPGF denotes industrial temperature grade, and this specification is validated across process corners and voltage extremes.
Does the TSB12LV21BIPGF support both PCI bus master and slave functions?
Yes, the TSB12LV21BIPGF supports full PCI Local Bus Specification Rev. 2.1 dual-role operation: it acts as a bus master for DMA transfers to and from 1394, local bus, and PCI memory, and as a slave for CPU-initiated read/write access to its internal configuration and control registers. This capability is implemented in hardware and documented in the SLLA213 datasheet section "PCI Interface Overview" with timing diagrams confirming burst transfer support up to 33 MHz.
How does the 4 KB FIFO in the TSB12LV21BIPGF improve system design?
The 4 KB configurable FIFO in the TSB12LV21BIPGF eliminates the need for external FIFO memory by allowing dynamic partitioning into separate buffers for 1394 receive, asynchronous transmit, and isochronous transmit operations. Each buffer size is programmable via register writes, enabling optimized latency and throughput trade-offs per application - for example, allocating 2 KB to isosync receive for video streaming while reserving 1 KB for async control packets in the TSB12LV21BIPGF.
What is the purpose of the ZV (Zoomed Video) port on the TSB12LV21BIPGF?
The ZV port on the TSB12LV21BIPGF is a dedicated 16-bit local bus interface designed to transfer uncompressed digital video frames directly from a 1394-connected camera to external video processing hardware, bypassing the PCI bus entirely. This reduces host CPU load and PCI bandwidth consumption, enabling real-time ingestion of DV-format or raw YUV streams - a capability confirmed in the SLLA213 datasheet's "Local Bus Interface" section and used in professional video capture cards implementing the TSB12LV21BIPGF.
Is the TSB12LV21BIPGF still in active production?
No, the TSB12LV21BIPGF is marked as OBSOLETE by Texas Instruments per the official packaging information table in SLLA213. While Aetrix Electronics maintains legacy inventory and traceable sourcing for ongoing production support, new designs should consider the active TSB12LV21BPGF variant (commercial temp) or evaluate TI's newer interface solutions. Obsolescence status is based on TI's published marketing status, not functional discontinuation.
