TLK10034: 1000BASE-KX Support Without Firmware/Registry Update / XFI Connection Support

Justin Muzzy

Part Number: TLK10034
Other Parts Discussed in Thread: TLK10232, , TLK10031

Tool/software:

Hello,

I am trying to ascertain the following for the TLK10034, TLK10031, and TLK10232 series PHYs.

1.  Will the PHYs support both 10GBASE-KR and 1000BASE-KX "as-is" with no firmware load or registry update required?  If registry update is required, is this in non-volatile memory?  If firmware is required, is external Flash required for storage?

2.  Will the PHYs support 10GBASE-R (non-backplane levels) AND 1000BASE-X? The datasheet says it will support 10GBASE-R but does not mention 1000BASE-X Is any registry updates or firmware required?

3.  I am trying to connect to a Marvell 88X3340 quad-port IC, via XFI.   The datasheet for the TLK10034 says it supports XFI (see below), but does not specify the proper connection or strapping/mode settings.  Can I use the TLK10034 via XFI as described, and what would be the proper pin connections?

Thank You for any help!

    1. These devices require configuration of registers.  These are volatile registers.

    Please see attached document.

    2. My understanding is that you're interested in using the TLK10232 with SFP/SFP+.  The data sheet notes that both SFP and SFP+ are supported.

    3. I would recommend following guidance for 10G-KR bringup.  You will then configure the TLK10232 with link training, FEC, and auto negotiation disabled.

    Thanks,
