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.
APPLICATIONS
• VCTCXO for mobile phones
• VCTCXO for other telecommunications
systems
