TLK10034: Using TLK10034 in XAUI to 10GBASE-R mode

Part Number: TLK10034

Hi,

We are looking for a Quad Port XAUI to 10GBASE-R/XFI converter device for below application,

Processor/MAC with XAUI interface <---> TLK10034 with XAUI interface at  host side & 10G-BASE-R at line side <---> Mult-rate 10G Phy with 10GBASE-R at host side & 10GBASE-R/SGMII at Line side <---> SFP+/SFP for 10G/1G.

Here the XAUI to 10GBASE-R converter is required as the Processor supports only XAUI (10G) and we need to support 10G/1G using a Multi-rate Phy.

Let me know if TLK10034 is the right device for this application.

Regards,

Jaison

    Hi,

    The TLK10034 may indeed be used as a XAUI to SFI PHY SerDes. The chip also supports legacy 1G rate. You may refer to its datasheet for configuration instructions.

    Hi,

    Here we need to run the interface at two speeds as follows,

    1. Processor/MAC at 10G XAUI <---> 10G (SFP+) , We are sure, TLK10034 will support this.

    2. Processor/MAC at 10G XAUI <---> 1G (SFP) , Not sure TLK10034 can run in this mode (Low speed side at XAUI rate & High speed side at 1G rate). This is why we went for another phy with rate matching capabilities.
