HALF SIZE VOLTAGE CONTROLLED CRYSTAL OSCILLATORS
VC-81&83 Series
The VC-81 & VC-83 series is half size
voltage controlled crystal oscillator de-
signed primarily for use in phase locked
loops, phase shift keying and other tel-
ecommunication applications such as
ADSL, Cable modem etc. VC-81 is 5V
power supply and VC-83 is 3.3V power
Supply.
