Virtex 6 - GTX support

Hi,

 

My question is,

 

Whether Virtex 6 GTX can support the "1000 Base- BX" lines to get directly interfaced ? Hope I have to use " Ethernet 1000BASE-X PCS/PMA or SGMII" logic core for this, if it supported.

In the design, we have to connect the AMC port0:1 directly to the Virtex 6 GTX using this Logic core. Is it feasible ?

Re: Virtex 6 - GTX support

Thanks for the Detail.

 

As you said, V6 can support 1000Base-X. But I don't know what is the exact difference between 1000Base-X and 1000Base-BX ? If there is no difference, I can use this same.

Re: Virtex 6 - GTX support

Hi Vijayan,

 

There is no IP core called 1000Base-BX. from XIlinx.

 

Xilinx only have 1000Base-X and 1000Base-T cores

Thanks and Regards

Re: Virtex 6 - GTX support

Hello,

 

i have a similar configuration with a Spartan 6 LX75T. I would like to interface a Marvell Switch Chip over 1000Base-BX. Is the only difference between 1000Base-X and BX the 1000 Mb/s speed, full duplex and flow control options? In this case, the 1000Base-X ip core is compliant !?

 

Thank you,

 

Thomas

Re: Virtex 6 - GTX support

Hi Danoz,

 

1000Base-X is similar to 1000Base-BX. BX is the Backplane varriant with fixed 1000Mbps. You have to set 1000 Forced and no Auto Neg on the PHYs. The IP Core should support this.

 

Bye,

Thomas
