MAS9278
IC for 10.00 – 30.00 MHz VCXO
Low Power
Wide Supply Voltage Range
True Sine Wave Output
Very High Level of Integration
Integrated Varactor
Electrically Trimmable
Very Low Phase Noise
Low Cost
DESCRIPTION
The MAS9278 is an integrated circuit well suited to
build VCXO for mobile communication. The crystal
offset trimming is done through a serial bus and
the calibration information is stored in an internal
PROM.
FEATURES
Very small size
Minor current draw
Wide operating temperature range
Phase noise <-130 dBc/Hz at 1 kHz offset
Programmable Vc sensitivity
BLOCK DIAGRAM
To build a VCXO only one additional component, a
crystal, is needed.
APPLICATIONS
VCXO for mobile phones
VCXO for other telecommunications systems
Replacement for TCXO modules
