Note 1: An RS < 15 Ω crystal provides 56 MHz maximum frequency (i.e. negative resistance typically 30 Ω). With
an RS = 70 Ω crystal the maximum frequency is typically 40 MHz (i.e. negative resistance typically 110 Ω).
Note 2: VC sensitivity value depends on the crystal used. With a 30 ppm/pF crystal typical values are
MAS9283AN
MAS9283AT – AX > 50 ppm/V.
–
AR > 90 ppm/V, MAS9283AA
–
AE > 75 ppm/V, MAS9283AG
–
AL > 60 ppm/V,
Note 3: If the PD pin is floating the output buffer is active. Oscillator is always running.
