DESCRIPTION
The MAS9271 is an integrated circuit well suited to make initial offset trimming of the crystal in oscillator. The trimming is done by a serial bus and the calibration information is stored in an internal PROM. To build a Precision Crystal Oscillator (PXO) only one additional component, a crystal is needed.

FEATURES
• Very small size
• Minimum current draw
• Wide operating temperature range
• Phase noise <-130 dBc/Hz at 1 kHz offset
• Square wave output

APPLICATIONS
• PXO for data terminals
• PXO for telecommunication applications
• PXO for computer application
