Hi,
I am not to familiar with the MTBF derivation and need to understand it and also confirm what the MTBF equation of a standard 2 Flip-flop synchronizer is. Please let me know if the below equations are correct:
MTBF of a single flop synchronizer = exp(Tres/τ)/ (Fclk*Fd*To)
MTBF of a double flop synchronizer = exp((Tres+Tclk-Tsu2)/τ)/ (Fclk^2*Fd*To^2)
Where:
Tres = resolution time of the FF
τ = FF const
Fclk/Tclk = Frequency/Period of clock to FFs
Fd = data frequency
To = suseceptible window taken into consideration
Tsu2 = setup time of second FF in 2 FF sync
Reference :

(Calculating MTBF for a 2-stage synchronizer)
If anyone has materials or a reference of a detailed explanation of the derivations or could confirm if the equations are correct it would be really healpful.
Thanks
