MAS9270

DA9270.008 11 September 2006 MAS9270 IC FOR 10.00 – 30.00 MHz VCTCXO • • • • • • • DESCRIPTION The MAS9270 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 crystal is required. The compensation method is fully analog, working continuously without generating any steps or other interference. Wide Supply Voltage Range True Sine Wave Output Very High Level of Integration Electrically Trimmable Very Low Phase Noise Low Cost Minimum Operating Temperature –40 ° C FEATURES • • • • • • Very small size Minor current draw W ide operating temperature range Phase noise
