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
