Anyone used new SMSC LAN9118 MAC/PHY yet?

Hi,

Has anyone used new SMSC LAN9118 MAC/PHY yet? It addresses a lot of the shortcomings of the LAN91C111 and should be capable of much better performance. I'm considering it for a new design but would like to hear from anyone who might have been there already. To get the most from the part I'll need to do a reasonable amount of development and so would be particularly interested in hearing from anyone with any "gotchas" they've hit.

Mark.

    Hi Mark,

    we are the SMSC 9117 in a design as MAC/PHY. Its the small brother of the 9118 with a 16 bit databus. It offers some nice features. At the moment I'm writing driver for the chip. But no performance test are done yet.

    I my eyes the configurable data alignment is one of the best feature. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

    kind regards

    Hi Joern,

    Have you done any throughput tests on your SMSC 9117?

    Regards,

    Louis.

    Hi Louis,

    i only wrote the basic driver for the SMSC and made no performance measurements.

    At the moment I&#39;m testing the DM9000A from Davicom with integrated TCP/UDP/IP checksum calculation. The first figures look very good. 2.8 MBytes/s in UDP mode (P2P) without any optimization.

    Kind regards

    Just out of curiosity, have you done any comparisons to any other Ethernet systems on the NIOS platform?

    I have done some benchmarks with the 91C111 from SMSC and now working with the Davicom MAC/PHY.
