MAS9280

Manufacturer Part Number
MAS9280
Description
IC FOR 18.00 - 40.00 MHz VCTCXO
Manufacturer
MAS
Datasheet
DESCRIPTION
The MAS9280 is an integrated circuit well suited to
build
Temperature calibration is achieved in three
calibration temperatures only. The trimming is done
through a serial bus and the calibration information
is stored in an internal PROM. This means no
rework for trimming is needed.

APPLICATIONS
Vref
To build a VCTCXO additionally only a crystal is
required. The compensation method is fully analog,
working continuously without generating any steps
or other interference.
Divider function allows the usage of double
frequency crystal.
Min. Supply Voltage 2.4 V
Max. Frequency 40 MHz
True Sine Wave Output
Frequency Stability +/- 1.5 ppm
Suitable Also for Low Pull
Crystals
Very Low Phase Noise
