Cost-effective route to FireWire control
Texas Instruments has developed a new cost-effective integrated 1394a link-layer controller and two-port physical-layer controller
Texas Instruments has developed a new cost-effective, integrated 1394a link-layer-controller and two-port physical-layer-controller (PHY). This cost-effective technology, which has a PCI host interface option, gives designers of multimedia applications, such as set-top boxes, DVD player/recorder, digital TV and digital VCR, an off-the-shelf component that facilitates the communication of compressed A/V data (ie DV, MPEG-TS, DirecTV TS) and digital audio according to the IEC61883 standard.

The TSB43DA42 and TSB43DB42 link and PHY each include three high-speed data interface (HSDI) ports.
Each port, which supports I/O of data, is dedicated to an isochronous datapath and can be independently configured to transmit/receive to and from 1394.
Additionally, all three ports support seamless connections to the various codecs on the market.
The integrated two-port PHY is capable of communicating at 400, 200 or 100Mbit/s.
'In the consumer electronics market it is necessary that devices be able to communicate A/V data efficiently and effectively', said Cecelia Smith, Marketing Manager for TI's Consumer Networking Group.
'With cost effective integration, fast transmit speeds and high levels of content protection, TI's technology meets this and many more industry requirements'.
Equipped with digital transmission content protection (DTCP), the TSB43DA42 can handle all of the formatting of the IEC61883 packets.
To do this, the device must first be configured by an external CPU which is connected to the host interface using either a PCI or SRAM/68K bus.
The TSB43DB42 is pin-for-pin compatible with the TSB43DA42, but does not include DTCP.
When transmitting to the 1394 network, the codecs will be responsible for outputting the compressed data, and the device will generate and output the IEC61883 packet containing the data.
When receiving data from the 1394 network, TSB43DA42 will remove the 1394 headers and timestamps from the IEC61883 packet and then output the compressed A/V data to the codec.
The TSB43DA42 and the TSB43DB42 are available now in 196-pin MicroStar BGA 15 x 15mm packages.
Suggested resale pricing in quantities of 1000 is $8.25 for the TSB43DA42 and $7.85 for the TSB43DB42.
