MAS9278

IC for 10.00 – 30.00 MHz VCXO

• Low Power

• Wide Supply Voltage Range

• True Sine Wave Output

• Very High Level of Integration

• Integrated Varactor

• Electrically Trimmable

• Very Low Phase Noise

• Low Cost

DESCRIPTION

The MAS9278 is an integrated circuit well suited to

build VCXO for mobile communication. The crystal

offset trimming is done through a serial bus and

the calibration information is stored in an internal

PROM.

FEATURES

• Very small size

• Minor current draw

• Wide operating temperature range

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

• Programmable Vc sensitivity

BLOCK DIAGRAM

To build a VCXO only one additional component, a

crystal, is needed.

APPLICATIONS

• VCXO for mobile phones

• VCXO for other telecommunications systems

• Replacement for TCXO modules
