after 10GEMAC IS interfaced to 10BASE_R, should i interface directly to SFP+ ??? or should i connect to GTX transceiver in VC707???

Jump to solution

HAI

 

i have to interface 10GE MAC to SFP+ in vc707 board, i have learnt from here that, i have to first interface 10GEMAC with 10GBASE_R and then to SFP+.

 

10GBASE_R ip is available from vivado. in this IP there are lot of input/output ports regarding transreceiver, so i am confused , should i directly 10GBASE_R to sfp+ or should i connect to something else ??????????????

 

thanks and regards

sir, i want to know wheather this 10GBASE_R has inbuild GTXE2 transceiver????? there are lot of signals like

gttxreset
gtrxreset
qplllock
qplloutclk
qplloutrefclk
drp_den_i
drp_dwe

these all are input to transreceiver, i dont know how to handle this signals,

do i have to interface transreceiver code before 10GBASE_R ???

Hi Akram,

 

You can directly connect the transceiver pins to the SFP+.

 

Find the required connection between the SFP+ and the corresponding FPGA pins in the below document.

 

Have a look at page 40.

The status signal pins can be found from the schematic.

Regards,

Satish
