MAS9276
IC for 10.00 – 30.00 MHz VCTCXO
DESCRIPTION
MAS9276 is integrated circuit well suited to build
VCTCXO for mobile communications. Temperature
calibration is achieved at three calibration
temperatures only. The trimming is done through a
serial bus and the calibration information is stored
in an internal PROM. This means that no rework
for trimming is needed.
FEATURES
Very small size
Minimal current consumption
Wide operating temperature range
Phase noise <-120 dBc/Hz at 100 Hz offset
Programmable Vc sensitivity
BLOCK DIAGRAM
Very High Control Voltage
Sensitivity
True Sinewave Output
Electrically Trimmable
Very Low Phase Noise
Low Power
Low Cost
To build a VCTCXO only a crystal is required in
addition to MAS9276. The compensation method
is fully analog, working continuously without
generating any steps or other interference.
