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. To build a VCXO only one additional component, a crystal is needed.

FEATURES
• Very small size
• Minor current draw
• Wide operating temperature range
• Phase noise <-130 dBc/Hz at 1 kHz offset
• Square wave output

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