Crystal oscillator simulation
The initial intention for this posting was to title it "Crystal Oscillator Blues," reflecting the challenges faced in constructing the crystal oscillator for the GPS Disciplined Oscillator (GPSDO), as mentioned in a previous post. However, there have been some positive...
clock circuit
The crystal-controlled SoftRock receivers developed by Tony Parks (KB9YIG) have played a significant role in introducing many individuals to Software Defined Radio (SDR). For those who prefer not to be limited to a single frequency, the SoftRock Ensemble receivers utilize...
Incorrect frequency from crystal oscillator
An old Eistar SJ-1 digital pulser has been acquired. However, the frequency it generates is consistently 66% of the expected output. The frequency observed at the frequency stage (Pin 11) is 66% of the 16 MHz crystal, which equates to...
Parallel-mode aperiodic crystal oscillator
The crystal is positioned between the collector of the output stage and the base of the input stage. The oscillation frequency can be accurately adjusted using the trimmer capacitor CI. This circuit operates within a frequency range of 500 kHz...
1024kHz and 4kHz square-wave output circuit
The circuit SJT is a 1024 kHz warming crystal oscillator. The circuit is illustrated in the accompanying chart. Due to the low output signal level, a transistor (VT1) is employed as a buffer amplifier. The base bias resistor (R2) of...
Colpitts Crystal Oscillator
A Crystal Colpitts oscillator can be constructed using a parallel mode crystal and a transistor. The circuit is depicted in the accompanying figure. In this configuration, an inductance is utilized.
The Crystal Colpitts oscillator is a type of electronic oscillator that...
Switchable Output Crystal Oscillator
Switchable Output Crystal Oscillator Circuit. This oscillator circuit allows crystals to be electronically switched using logic commands. The circuit is best understood by initially ignoring all crystals. Furthermore, assume that a...
