MAS9271
IC FOR 10.00 – 40.00 MHz PXO
• Low Power
• Wide Supply Voltage Range
• CMOS (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
