2. Guaranteed by design with a square wave signal (@25 °C, VDD=3.3 V /VPP = 400 mV / VDC=1 V) where

VDC is the DC component of the input signal.

3. Guaranteed by design with a square wave signal (@25 °C, VDD=1.71 V /VPP = 200 mV / VDC=0.8 V) where

VDC is the DC component of the input signal.

5. tSU(HSE) is the startup time measured from the moment it is enabled (by software) to a stabilized analog

bypass clock interface is reached. This value is measured with 200 mV peak-to-peak amplitude.
