Another step toward all-digital
As consumer electronics head toward becoming all digital, TI's TSB12LV41 link-layer controller will be one of the devices making the move possible.
The TSB12LV41, sometimes called MPEG2Lynx, is the first 1394 link-layer controller to automatically handle simultaneous bidirectional MPEG2 (motion picture expert group) or DSS (digital satellite system) streams and MPEG2/DSS and isochronous streams. It is capable of supporting simultaneous MPEG2/DSS/isochronous and asynchronous traffic, and it supports provisions of the Institute of Electronics and Electrical Engineers (IEEE) 1394-1995 standard.
The TSB12LV41 provides a 1394 interface for high-performance audio, video and data applications up to 200 megabits per second (Mbps). It's suited for set-top boxes (STBs), digital televisions, digital recording devices, multimedia tape and disk drives and other electronic equipment requiring MPEG2 formatted isochronous data transfer according to the proposed International Electro- technical Commission (IEC) 61883 standard.
Among its features is a multimode eight- or 16-bit interface that supports most available microprocessors and microcontrollers. The device automatically formats MPEG2/DSS packets, performs age filtering, detects lost cycle-start packets and generates and inspects the 32-bit cyclic redundancy check (CRC). It also supports non-MPEG2/DSS isochronous and asynchronous data transfer with an auto-packetization feature.
TSB12LV41, sampling now from TI, is scheduled to be available in 4Q97. For more information about the 1394 product family, visit TI's web page at:  http://www.ti.com/sc/1394.
