The TSB12LV41A provides a 1394 interface for high-performance audio, video, and data applications at up
to 200 Mbits/s. It is suitable for set-top boxes, multimedia tape, disk drives, and other consumer electronic
devices requiring MPEG-2 formatted isochronous data transfer according to the IEC61883 specification.
The TSB12LV41A also supports non-MPEG-2/DSS isochronous and asynchronous data transfer with an
auto-packetization feature.
The TSB12LV41A interfaces directly to several microprocessors and microcontrollers, including embedded
ARM processor, Intel 8051 and the Motorola 68000. The microprocessor interface supports both 8-bit and
16-bit data busses. It can also automatically transform addresses to interface to either big endian or little
endian type processors.
The bulky data interface (BDIF) is a 16-bit wide I/O port that enables both transmit and receive of DVB/DSS,
isochronous, and asynchronous data. This port is full-duplex, meaning it is capable of transmitting and
receiving 1394 packets simultaneously. A separate 8K-byte FIFO, accessible via the bulky data interface,
provides logically independent FIFOs for transmit and receive of isochronous, asynchronous, and MPEG2
compressed DVB/DSS data. The 8K-byte FIFO or bulky data FIFO can perform asynchronous packet
transmit retry up to 256 times with intervals up to 256 × 125 ms. The TSB12LV41A supports full-width
time-stamped offsets for MPEG2 compressed DVB/DSS transmit and receive, and also performs age
filtering functions. A 256-byte FIFO is used to transmit and receive asynchronous control packets.
