XIO2213A：1394 interface design

Part Number: XIO2213A
Other Parts Discussed in Thread: TSB82AA2B, XIO2001, TSB81BA3E

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.
