MAS9278A

DA9278.004 13 July 2006 MAS9278 IC for 10.00 – 30.00 MHz VCXO • • • • • • • • DESCRIPTION The MAS9278 is an integrated circuit well suited to build VCXO for mobile communication. The crystal offset trimming is done through a serial bus and the calibration information is stored in an internal PROM. To build a VCXO only one additional component, a crystal, is needed. Low Power Wide Supply Voltage Range True Sine Wave Output Very High Level of Integration Integrated Varactor Electrically Trimmable Very Low Phase Noise Low Cost FEATURES • • • • • Very small size Minor current draw W ide operating temperature range Phase noise
