description
The TSB12LV21 (PCILynx) provides a high-performance IEEE 1394-1995 interface with the capability to transfer data between the 1394 phy-link interface, the PCI bus interface, and external devices connected to the local bus interface. The 1394 phy-link interface provides the connection to the 1394 physical layer device and is supported by the on-board link layer controller (LLC). The LLC provides the control for transmitting and receiving 1394 packet data between the FIFO and phy-link interface at rates of 100 Mbit/s, 200 Mbit/s, and 400 Mbit/s. The link layer also provides the capability to receive status from the physical layer device and to access the physical layer control and status registers by the application software. An internal 1K-byte memory is provided that can be configured as multiple variable-size FIFOs and eliminates the need for external FIFOs. Separate FIFOs can be user configured to support 1394 receive, asynchronous transmit, and isochronous transmit transfer operations. The PCI interface supports 32-bit burst transfers up to 33 MHz and is capable of operating as both master and target devices. Configuration registers can be loaded from an external serial EEPROM, allowing board and system designers to assign their own unique identification codes. An autoboot mode allows data-moving systems (such as docking stations) to be designed to operate on the PCI bus without the need for a host CPU. The DMA controller uses packet control list (PCL) data structures to control the transfer of data and allow the DMA to operate without host CPU intervention. These PCLs can reside in PCI memory or in memory that is connected to the local bus port. The PCLs implement an instruction set that allows linking, conditional branching, 1394 data transfer control, auxiliary support commands, and status reporting. Five DMA channels are provided to accommodate programmable data types. PCLs can be chained together to form a channel control program that can be developed to support each DMA channel. Data can be stored in either big endian or little endian format eliminating the need for the host CPU to perform byte swapping. Data can be transferred to either 4-byte aligned locations to provide the highest performance or to nonaligned locations to provide the best memory use.

description (continued)
The RAM, ROM, AUX, ZV, and general purpose I/O (GPIO) ports collectively implement the local bus interface. These ports are mapped into the PCI address can be accessed either through the PCI bus or internal DMA transactions. Internal transactions do not appear on the external PCI bus, thereby conserving PCI bandwidth. DMA packet control lists or other data that may be stored in external RAM or ROM attached to the local bus interface. This further reduces PCI use and generally improves performance. The ZV local bus port is designed to transfer data from 1394 video devices to an external device connected to the PCILynx ZV port. This interface provides a method of receiving 1394 digital camera packets directly to a ZV-compliant device attached to the local bus interface. Built-in test registers, a dedicated test output terminal, and four GPIO terminals allow observation of internal states and provides a convenient software debug capability. Programmable interrupts are available to inform driver software of important events such as 1394 bus resets and DMA-to-PCL transfer completion. The 3.3-V internal operation provides reduced power consumption while maintaining compatibility with 5-V signaling environments. The PCI interface is compatible with both 3-V and 5-V PCI systems.

IMPORTANT NOTICE Texas Instruments (TI) reserves the right to make changes to its products or to discontinue any semiconductor product or service without notice, and advises its customers to obtain the latest version of relevant information to verify, before placing orders, that the information being relied on is current and complete. TI warrants performance of its semiconductor products and related software to the specifications applicable at the time of sale in accordance with TI's standard warranty. Testing and other quality control techniques are utilized to the extent TI deems necessary to support this warranty. Specific testing of all parameters of each device is not necessarily performed, except those mandated by government requirements. Certain applications using semiconductor products may involve potential risks of death, personal injury, or severe property or environmental damage ("Critical Applications"). TI SEMICONDUCTOR PRODUCTS ARE NOT DESIGNED, INTENDED, AUTHORIZED, OR WARRANTED TO BE SUITABLE FOR USE IN LIFE-SUPPORT APPLICATIONS, DEVICES OR SYSTEMS OR OTHER CRITICAL APPLICATIONS. Inclusion of TI products in such applications is understood to be fully at the risk of the customer. Use of TI products in such applications requires the written approval of an appropriate TI officer. Questions concerning potential risk applications should be directed to TI through a local SC sales office. In order to minimize risks associated with the customer's applications, adequate design and operating safeguards should be provided by the customer to minimize inherent or procedural hazards. TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein. Nor does TI warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right of TI covering or relating to any combination, machine, or process in which such semiconductor products or services might be or are used.
