MAIN CHARACTERISTICS

High input sensitivity:

200mVpkpk @ 60MHz

Low consumption:

3.5mA @ 3V for the two loops

Power supply voltage:

3V to 5V

Operating temperature range:

–25°C to +70°C

DESCRIPTION

The ST7162 is a dual frequency synthesizer in

High Speed CMOS technology for radio applica-

tions with a frequency up to 60MHz. The low

power consumption and high flexibility make it

well suitable for cordless CT0 applications in vari-

ous countries.
