Inputs pins must be prevent from floating.
Feedback inputs (FBIN,
FBIN
) may float when the device is in low power mode.
1. DC input signal voltage specifies the allowable dc execution of differential input.
2. Differential cross point voltage is expected to track variations of V
DDQ
and is the voltage at which
the differential signals must be crossing. (See figure1-1)
