How is TLK3134 configured for 10G Ethernet application?

I found this thread on the forum and was hoping you could answer a similar question. We are looking into doing a new product that takes 10G KX4 which looks like it is the same as 10G CX4 and converting it to SFP+ DAC. Do you have a chip or chip set for that?  Is the TLK3134 still the best part? Do you know if CX4 is the same as KX4 and if it will direct connect to the converter?

Thanks

Tom

    Hi Tom,

    We have several SerDes solutions that were designed to support applications such as these. Please take a look at the TLK10034 (quad channel), TLK10232 (dual channel), and the TLK10002 (dual channel) devices. I have several other solutions I could recommend here but lets start with these and see what you think. Please let me know where else I can help?

    Regards,

    Hi Tom,


    I think I might have jumped the gun on you here. Could you please elaborate on what your LS requirements are? The devices that I recommended above take in XAUI on their LS side and aggregate that up top a 10G link which can be XFI. The TLK3134 supports a parallel interface of 32 bits and converts that up to a XAUI output. The aggregate total of the four lanes of XAUI gives you an equivalent throughput of 10G. So the TLK3134 will not directly support XFI.

    We have had customers in the past design a two chip solution using the TLK3134 and the TLK10232. This type of implementation will get you from your parallel interface to an XFI compliant link. Please let me know what you think and we can explore this further and please let me know where else I can help?
