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. 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.
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
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
APPLICATIONS
* * VCTCXO for high end telecommunications systems TCXO for high end telecommunication systems

Note: Because the substrate of the die is internally connected to GND, the die has to be connected to GND or left floating. Make sure that GND is the first pad to be bonded. Pick-and-place and all component assembly are recommended to be performed in ESD protected area. Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The coordinates may vary depending on sawing width and location, however, distances between pads are accurate. Note 3: Valid for MAS9279A1, A3, A5 and A7. In MAS9279A2, A4, A6 and A8 TE1 and TE2 pins have been swapped.
