Occasional ContributorStratix 10 Calibration Native Phy and Atx Pll
Hello. I have read document xcvr h/l tile stratix 10, and tested my project in ModelSim I have 4 channels native phy with multiple profiles saved and embedded reconfiguration streamer 2 Atx pll with...
Hi,
Q1. Can I use fpll as MCGB and dynamic reconfiguration it with profiles?
Ans - Yes.
Q2. Can I use fpll with mcgb and dynamic reconfiguration and atx pll with mcgb without dynamic reconfiguration. They goes to native phy serial clk 0 and 1. And I can mux them in native phy via reconfiguration interface.
Ans - It should be, please looked into the IP, If there are profiles in the dynamic reconfiguration tab, then profiles are supported.
Q3. Can i use fpll in Transceiver mode for 7GHz?
Ans - Maximum frequency for fPLL is 12.5Gbps (6250MHz).
Thank you

Occasional ContributorThanks for explaining.
Yes, I failing to meet protocol specs.
I thought about another scheme to use TX PLLs and decided to use
One fpll in Transceiver mode with MCGB, with multiple profiles.
One ATX pll with also MCGB for higher speed, without reconfiguration. Mcgb because of need for 4 channels.
So fpll recalibration time meets time requirements.
And Native Phy with 2 tx pll inputs.
I read xcvr user guide and have some questions about 6.15 "unsupported features", can you explain about Reconfiguration MCGB and switching between two MCGB
