MAS1174

IC FOR 10.00 – 30.00 MHz VCXO

• 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 MAS1174 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.To build a

VCXO only two additional components, a varactor

FEATURES

• Very small size

• Minor current draw

• Wide operating temperature range

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

and a crystal are needed. The compensation

method is fully analog. IC compensation work is

continuous without generating any steps or other

interferences.

APPLICATIONS

• VCXO to mobile phones

• VCXO to other telecommunications systems
