MAS1175
IC FOR 10.00 – 20.00 MHz VCTCXO
• Low Power
• Wide Supply Voltage Range
• True Sine Wave Output
• Very High Level of Integration
• Electrically Trimmable
• Very Low Phase Noise
• Low Cost
DESCRIPTION
The MAS1175 is an integrated circuit well suited to
build VCTCXO for mobile communication. Only two
external components are needed. Temperature
calibration is achieved with three calibration points
only. The trimming is done through a serial bus and
the calibration information is stored in an internal
PROM.
To build a VCTCXO only two additional
components, a varactor and a crystal are needed.
The compensation method is fully analog. IC
compensation work is continuous without
generating any steps or other interferences.
FEATURES
• Very small size
• Minimum current draw
• Wide operating temperature range
• Phase noise <-130 dBc/Hz at 1 kHz offset
• VCTCXO for mobile phones
APPLICATIONS
• VCTCXO for other telecommunications
systems
