Note 1: An RS < 20 Ω crystal provides 36 MHz maximum frequency. With an RS = 70 Ω crystal the maximum

frequency is typically 20 MHz.

Note 2: VC sensitivity value depends on the crystal used. With a 30 ppm/pF crystal typical values are:

A1 > 100 ppm/V, B2 > 75 ppm/V, B3 > 60 ppm/V, C2 > 75 ppm/V, C3 > 60 ppm/V, C4 > 55 ppm/V.

Note 3: MAS9275A, MAS9275B

Note 4: MAS9275C

Note 5: If the Tri State Output Buffer is floating (i.e., PD pin not connected), the oscillator is ON in all models

(MAS9275A, -B and -C)
