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
