SDI II Tx Instances

Hi, I am looking for SDI II multi-rate multi Tx instances for C10 GX. I followed the information on the UG-01125 and add the commands in the qsf. "set_instance_assignment -name XCVR_RECONFIG...

Hi Bin,


Thanks for your update. Yes, your understanding is correct, the assignment is to fit 1 TX only instance and 1 RX only instance into the one physical transceiver channel. If you have multiple TX only and RX only instances, then you will need to set the assignment to each pair with different reconfig group number. You would need to decide which pair of instances to fit into which transceiver channel.


Please let me know if this answer your inquiry. If not, please help to further elaborate your inquiry. Thank you.

Hi Chee_Pin,

My goal now is to fit Quad-SDI Tx and Rx into a bank in C10 GX.

I looked the example generated by the IP core.

The Tx design didn't include any reconfiguration logic.

Instead it just had transceiver phy, sdi ip, reset controller and fPLL.

Then for a Quad "bonding" design, I might need to have all 4-channels share the same fPLL and reset controller ?

Otherwise if I followed the reference, I need to have 4 fPLLs, the resource is not enough..

Am my understanding correct?

For the Rx side, I saw reconfiguration in the reference.

Then how could I implement a Quad SDI Rx ?

Or where I can find related information ?

Thank you!

Best Regards,

Bin
