MAS1178

IC FOR 10.00 – 20.00 MHz VCXO

• Low Power

• Wide Supply Voltage Range

• Square Wave Output

• Very High Level of Integration

•

Electrically Trimmable

• Very Low Phase Noise

• Low Cost

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.
