RGMII to SGMII Interface

Other Parts Discussed in Thread: TLK3132

Hi and good morning.

I’m not sure if you’re also supporting the Ethernet Transceiver Products.

The question is to interface a Avago SGMII Transceiver with a FPGA with (R)GMII- Interface only.

I’ve found an Appnote (SPRAAU2A) where the problem was mentioned (9.3.2, Page 15):

"Note that the TCI6486/C6472 EVM board uses the SGMII-to-RGMII Ethernet PHY (88E1143) to convert

from the DSPs' RGMII ports to the SGMII interfaces needed by the Gigabit Ethernet Switch. No Gigabit

Ethernet Switches with RGMII ports could be located. Texas Instruments also provides an RGMII PHY

that has been proven in this application. It is a 6-port RGMII Gigabit Ethernet PHY known as the TLK2226.

For detailed information regarding the TLK2226, see the link:

http://focus.ti.com/docs/prod/folders/print/tlk2226.html."

 

So I’m searching for a Transceiver with two Ports to interface between SGMII and RGMII. The TLK3132 looks great but I’m not sure if it’s working. Can you give me an advice?

 

 Thanks a lot!

Best regards
