What PHY interface does the MGBT1 SFP Use ?

cjrice · ‎12-30-2009

I am using the Cisco MGBT1 SFP Transceiver in an SFP Module Interface on a Xilinx ML555 development board. I need to configure the MAC that I am using to talk to the MGBT1, but don’t know what PHY interface the MGBT1 supports. Does it use SGMII, RGMII, GMII, MII or 100Base-X PHY interface? Detailed specifications on the MGBT1 would be very helpful, but I can not find them on your site. Do you use transceivers manufactured by Marvell? If so, which one.

Hi,

I'll see if i can refer this to the appropriate Product Manager for input.

The interface to the board is 2-pair SERDES and the interface to the network is SGMII. I will contact you directly on more detailed information.

No the MGBT1 is not SGMII it is 1000base-X.

I have just got an MGBT1 SFP working with a Xilinx Virtex5 hard TEMAC.

So far I have not found a way to access the PHY registers in the MGBT1. Other SFP's I have tried allow access to the PHY via the IIC interface.
