Functional Description
Fail-Safe Input (FSI)
The input includes a special failsafe circuit to sense
the amplitude of the input signal and to latch the
outputs when there is no input signal present, or
when the amplitude of the input signal drops
sufficiently
below
100mVPK (200mVPP), typically
30mVPK. Maximum frequency of the SY58609U is
limited by the FSI function.
Input Clock Failure Case
If the input clock fails to a floating, static, or extremely
low signal swing, the FSI function will eliminate a
metastable condition and guarantee a stable output.
No ringing and no undetermined state will occur at the
output under these conditions.
Note that the FSI function will not prevent duty cycle
distortion in case of a slowly deteriorating (but still
toggling) input signal. Due to the FSI function, the
propagation delay will depend on rise and fall time of
the input signal and on its amplitude. Refer to “Typical
Characteristics” for detailed information.
