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