XIO2213A：1394 interface design

Part Number: XIO2213A
Other Parts Discussed in Thread: TSB82AA2B, XIO2001, TSB81BA3E, TSB82AF15-EP, TSB41BA3F-EP

Tool/software:

HI team，

 I'm going to design a circuit with 1394 interface. I appreciate TI's xio2213a，but it is NOT RECOMMENDED FOR NEW DESIGNS. and  there are other discrete products like TSB82AA2B+tsb81ba3, That is in the form of a PHY+ controller .In my opinion ,the xio2213a is PHY+ controller +PCIe bridge ,so it is much easier to use .am i wrong? if i use xio2213a , only configure connect+xio2213a+ FPGA ，Can I achieve a normal 1394 interface transmission link ？If i use TSB82AA2B+tsb81ba3，can i use STM32F4 as the PCI processor ？Looking forward to reply.

Regards

    Yes; the XIO223A/B simply combines a PCIe/PCI bridge (=XIO2001), an OHCI controller, and a PHY (=TSB81BA3E).

    Which controller to use depends on what CPU bus interface you have. With PCI, you have to use the TSB82AA2B. With PCIe, you have to use the XIO2213A, or use a PCI/PCIe bridge; and the XIO is easier to use, as long as TI makes it.

    As far as I know, the STM32F4 does not support PCI.

    Nowadays, IEEE-1394 is pretty much a legacy interface. I am not able to predict whether the TSB82AA2B or the XIO2213A will have a better lifetime.

    Thank you ,Clemens. As we know ,normal 1394 transmission distance is only 4.5m. The description of “1394 FireWire(R) Quick Reference Card” said that • Longer distances: 100 meters with GOF and CAT5; 50 meters with POF

    So， how to achieve a distance of 100m,shoufd i need a optical module ？Can a regular Ethernet optical module convert 1394 signals into optical signals？

    Thank you again

    Yes ，Clemens , "Nowadays, IEEE-1394 is pretty much a legacy interface. I am not able to predict whether the TSB82AA2B or the XIO2213A will have a better lifetime." There is a new product TSB82AF15-EP maybe substitute XIO2213A

    Hi Bing:

       TSB41BA3F-EP can supports connection to CAT5 cable transceiver by setting ports to be beta-only, 400-Mbps-only, 200- Mbps-only or 100-Mbps-only.
