description  
The TSB12LV21A (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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
