function
BA7042
The BA7042 is a monolithic IC comprising a VCO (voltage controlled oscillator) with sensitivity adjusting capabilities.
The oscillation frequency can be set with an external constant, and is controlled according to the control voltage. The
BA7042 can be used to produce high-modulation-factor FM signals by superimposing its control voltage with AC signals,
and to configure a PLL circuit just by attaching a frequency divider and a phase comparator.
Applications
FM intercom
FM wireless microphone
FSK modem
Features
1) The number of external components is minimized.
2) Internal control amplifier for the VCO.
3) Oscillation frequency can be set with an external
constant.
4) Maximum oscillation frequency of 18MHz.
5) DIP 8-pin package.
