DA9280.003 13 July 2006 MAS9280 This is preliminary information on a new product under development. Micro Analog Systems Oy reserves the right to make any changes without notice. IC FOR 18.00 – 40.00 MHz VCTCXO • • • • • • Min. Supply Voltage 2.4 V Max. Frequency 40 MHz True Sine Wave Output Frequency Stability +/- 1.5 ppm Suitable Also for Low Pull Crystals Very Low Phase Noise DESCRIPTION The MAS9280 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. To build a VCTCXO additionally only a crystal is required. The compensation method is fully analog, working continuously without generating any steps or other interference. Divider function allows the usage of double frequency crystal. FEATURES • • • • • • Very small size Minimum Vdd 2.4V No voltage reference capacitor needed Phase noise
