Use Marvell 88E1111 PHY without using TSE IP

Hey! I need to use the 10/100/1000 Ethernet interface from Stratix V for a project. So far, I have successfully tested this interface in two cases: 1) using the full Triple Speed IP (MAC + 1000BA...

Hi,


May I know are you trying to look for free IP since you brought up IP suite license concern ?


The other option that I can think of is to use "transceiver NativePHY Intel Stratix V FPGA IP" or "ALTLVDS_RX or ALTLVDS_TX"

  • However, these are not Ethernet PHY IP
  • It's just a skeleton PHY IP that user can customize and build whatever PHY protocol. For instance, Ethernet protocol
  • I think these are free IP but pls confirm with your local distributor


Thanks.


Regards,

dlim

    Hi, again!

    Thank you for the fast response.

    Yes, I am looking for a way to use the Ethernet interface without requiring an additional license. I thought that the license for the TSE IP was due to the MAC (which is soft-logic) and not due to the PCS/PMA (which is hard-logic) as shown below:

    I have already tried to use the Transceiver Native PHY Intel Stratix V FPGA IP. In your design store, there is this great example for Arria 10, however, as far as I understood, it seems that the serial connection only supports high-speed ethernet using SFP+ ports instead of RJ45. I need to use the RJ45 interface from the Stratix V (which is the one connected to the 88E1111 chip).

    What I need to understand is how to use the hard IPs that TSE uses for PCS/PMA as I already have a MAC IP. For instance, for the 10Gb connection, we can use the 10GBASE-R PHY IP for free and then develop our own MAC IP using XGMII interface. For 100M/1G, we developed the MAC IP using GMII interface and we need the PHY IP for interfacing the 88E1111 via SGMII.

    Am I missing something?
