Could you please provide a default configuration of DS250DF410(CDR)? We use SMBUS slave mode, so we can output when there is an input signal.

input signal datarate is 20G

Hi,

Note that the DS250DF410 is designed to lock to signals between 20.2752 Gbps and 25.8 Gbps (as well as subrates of this). Is it correct that your data is 20 Gbps? This is outside of the supported range of the CDR.

Thanks,

Drew

Hi,

I would recommend leveraging SigCon Architect, which can be used to generate device configurations.

I've attached a configuration with default DS250DF410 settings expect for CDR set to 20.5 Gbps.

ds250df410-20p5gbps.cfg

Thanks,

Drew

Is the register configuration data in this setting the register default or used to configure CDR set to 20.5 Gbps

such as 0x2F Channel 0_0x2F 54.

Is the default data 54 or the data I need to configure 54.

Hi,

The registers were configured for CDR set to 20.5 Gbps. You can confirm by looking at registers 0x60-0x64.

Thanks,

Drew
