IC FOR 10.00 – 20.00 MHz VCXO
Low Power
Wide Supply Voltage Range
Square Wave Output
Very High Level of Integration
•
Electrically Trimmable
•
Very Low Phase Noise
•
Low Cost
•
•
•
•
To build a VCXO only one additional component, a
crystal is needed.
DESCRIPTION
The MAS1178 is an integrated circuit well suited to
build VCXO for mobile communication. The
trimming is done by a serial bus and the calibration
information is stored in an internal PROM.
