MAS9271

IC FOR 10.00 – 40.00 MHz PXO

• Low Power

• Wide Supply Voltage Range

• Square Wave Output

• Very High Level of Integration

• Electrically Trimmable

• Very Low Phase Noise

• Low Cost

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.

FEATURES

• Very small size

• Minimum current draw

• Wide operating temperature range

• Phase noise <-130 dBc/Hz at 1 kHz offset

• Square wave output

BLOCK DIAGRAM

To build a Precision Crystal Oscillator (PXO) only

one additional component, a crystal is needed.

APPLICATIONS

• PXO for data terminals

• PXO for telecommunication applications

• PXO for computer application
