Working Principle

The 8N4QV01KG-1124CDI employs a combination of analog and digital components to operate. While the output frequency is digitally controlled by a multi-bit counter, the analog components come into play during the duty cycle setting and external control operation.

The frequency of the pulse output is set with a voltage control oscillator (VCO) and an adjustable resistor network. This network allows the user to set the output frequency of the 8N4QV01KG-1124CDI within the range of 0.5 to 20MHz. The pulse width is then controlled by a phase-locked loop (PLL) circuit, which synchronizes the phase of the pulse with the output frequency.

The external control interface is used to allow external devices, such as computers and other industrial equipment, to monitor and control the 8N4QV01KG-1124CDI. The external control interface is capable of receiving commands from the external device to control the output parameters of the 8N4QV01KG-1124CDI, such as the output frequency and duty cycle.

Conclusion

The 8N4QV01KG-1124CDI is a programmable timer and oscillator designed for a range of applications. It offers accurate pulse width, pulse periods and pulse frequency outputs along with built-in functions and an external control interface. The 8N4QV01KG-1124CDI is equipped with analog and digital components which allow it to accurately control the output frequency of the pulse.
