I read ethernet 1000base user guide but that is not clear for me what is difference between SGMII and ethernet 1000base? SenVel SenVel. 0000389011 00000 n
MDI as usual for Copper Transformer interface. RGMII mode and RTBI mode, with the current mode being selected by the tbi input signal. I take it you want to interface a PHY to the RGMII controller on the i.MX6, but only run it at 10/100 speeds. 0000001362 00000 n

Both paths have an independent clock, 4 data signals and a control signal. In these case RGMII connect to MAC.
We're trying to understand the consequences of doing this vs. say having an SGMII interface hooked to that cage. 0000388519 00000 n

in first page I should select standard between 1000basex, SGMII or both of them. I've had that design constraint a couple of times, and generally, the most flexible option is to use a gigabit PHY running at 10/100 at all times. It has a clock speed of 125 MHz and 8 data bits in both directions. 0000254855 00000 n

The TLK3132 looks great but I’m not sure if it’s working. All postings and use of the content on this site are subject to the TI is a global semiconductor design and manufacturing company. Besides, SGMII/1000BASE-T is often used with SFP pluggable transceivers which have an I2C interface instead of MDIO for management registers access. The interface clock is sourced by the PHY. In some PHY the link to MAC is over SGMII. 0000389361 00000 n

On our product, the SFP cages are hooked up directly to the SerDes pins coming off the switch. The Ethernet transceivers that are supported in the Ethernet forum do not include an option for RGMII-to-SGMII.We are glad that we were able to resolve this issue, and will now proceed to close this thread.If you have further questions related to this thread, you may click "Ask a related question" below.

I’ve found an Appnote 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 No license, either express or implied, by estoppel or otherwise, is granted by TI. 0000001262 00000 n
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.So I’m searching for a Transceiver with two Ports to interface between SGMII and RGMII. x�]�A�����>����,K �����~��-�ڲ��8�����z�ȁ��
