MAS9279
IC FOR 10.00 – 52.00 MHz VCTCXO
DESCRIPTION
The MAS9279 is an integrated circuit well suited to
build high end VCTCXO for telecommunication.
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
• Minimal current consumption
• Wide operating temperature range
• Very low phase noise
• Programmable VC-sensitivity
• Minimum operating temperature –40 °C
• Oscillator frequency output f0/2 version
available
BLOCK DIAGRAM
• Fourth Order Compensation
• Frequency Stability +/- 0.3
ppm
• Wide Frequency Range
• Very Low Phase Noise
• Low Voltage
• Minimum Operating
Temperature –40 °C
• Tri State CMOS Output
To build a VCTCXO only crystal is required in
addition to MAS9279. The compensation method is
fully analog, working continuously without
generating any steps or other interference.
