SGMII 10/100 on P2020

[toddreed]

When using SGMII 10/100 on the P2020, is the output based on a slower clock instead of the 625Mhz clock?

Thanks,

Have a great day,

The P2020 SGMII signal  has fixed rate in according to the SGMII specification. To support 10 Mbps and 100 Mbps data rates, SGMII stretches the frame by replicating each frame byte 10 times for 100 Mbps and 100 times for 10 Mbps

Thank you Serguei.  So, with the replicated data,  would it look like 62.5 mhz or 6.25 mhz data on the line?

Have a great day,

It will not look like 62.5 mhz or 6.25 mhz data on the line. The SGMII signal  has fixed bit rate.
