Tool/software:
Hi Community,
I would like to understand the Serdes Tx parameters based on the spruho3b document.
§14.2.3 declares 4 parameters C0,C1,C2,CM where C0 is calculated from the CM,C1,C2 values. Equation (3) gives a relation between those values
And Indeed CM,C1,C2 can be adjusted by manually adjusted by software (registers do exist)
But in the same paragraph we can see another formula where C0+C1+CM = 1 (normalization) without any reference to C2. It is therefore explained that C0 only depends upon C1, CM and not C2
Could you explain please ?
In figure 14 we can see de-emphasis, preshoot and boost calculation but nothing depends on C2 value ! So what is the purpose of C2 then ? This is quite confusing
If you could give some explanations it would be great.
With best regards,
Bruno
