• Manufacturer Part Number: MAS9283
• Description: IC FOR 10.00 - 56.00 MHz VCXO
• Manufacturer: MAS

ELECTRICAL CHARACTERISTICS
Note 1: An R
an R
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.
Note 3: If the PD pin is floating the output buffer is active. Oscillator is always running.
IC OUTLINES
Note 1: MAS9283 pads are round with 80 µm diameter at opening.
Note 2: Die map reference is the actual left bottom corner of the sawn chip.
