Crystal Oscillator ICs

MAS

MAS6279 High-End VCTCXO

The MAS6279 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 EEPROM. To build a VCTCXO only a crystal is required in addition to MAS6279. The compensation method is fully analog, working continuously without generating any steps or other interference.


MAS6285 IC for Offset Trimming of Oscillators with Max. Frequency of 200 MHz

MAS6285 is capacitive digital to analog converter integrated circuit well suited to make initial offset trimming of the crystal oscillator. The trimming is done by a serial bus and the calibration information is stored in an internal PROM.


MAS6283 25.00-40.00 MHz VCXO with CMOS (Square Wave) Output

MAS6283 is an integrated circuit well suited to build a VCXO for telecommunication and other applications. To build a VCXO only one additional component, a crystal, is needed.
