MAS6282
IC FOR 6.50 – 40.00 MHz VCTCXO
• Min. Supply Voltage 2.6 V
• Max. Frequency 40 MHz
• True Sine Wave Output
• Frequency Stability ±2.0 ppm
• Suitable for Ultra Small
VCTCXO
• Very Low Phase Noise
DESCRIPTION
The MAS6282 is an integrated circuit well suited to
build VCTCXO for mobile communication.
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.
FEATURES
• Very small size
• Minimum Vdd 2.6V
• No voltage reference capacitor needed
• Programmable VC-sensitivity
• Divider option selectable by a PROM bit
• Output peak voltage (amplitude) option
selectable by a PROM bit
BLOCK DIAGRAM
To build a VCTCXO only a crystal is required in
addition to MAS6282. The compensation method is
fully analog, working continuously without
generating any steps or other interference.
Output is true sine wave resulting in lower
harmonics than with clipped sine wave output.
APPLICATIONS
• VCTCXO for mobile phones
• VCTCXO for other applications
