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
