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 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
• Minor current draw
• Wide operating temperature range
• Phase noise <-130 dBc/Hz at 1 kHz offset

APPLICATIONS
• VCXO to mobile phones
• VCXO to other telecommunications systems
