This traditional TTL configuration was obtained in a 1977 documentation. The supply must be made with 5 V and the capacitors can be changed for operation at other frequencies.
This oscillator can generate signals from 100 kHz to more than 50 MHz depending on the crystal used...
Found in a 1980s American documentation, this circuit appears with variations elsewhere in this...
This circuit was obtained in a 1969 documentation. The circuit modulates both the emitter current and...
