This device features a regular octal package, low power consumption, low power dissipation, a TTL/CMOS compatible interface and a wide operating temperature range. In addition, 8N4QV01LG-0047CDI has a choice of operating conditions such as 1ms, 10ms, 100ms. It is an ideal choice for applications requiring an accurate control over pulse timing.

Application Field

Programmable timers and oscillators such as 8N4QV01LG-0047CDI are mainly used in the fields of industrial automation, radar system, motion control and communication systems. Industrial automation applications include machine control, factory automation, HVAC and process control. Radar systems rely on oscillators to produce high frequency signals which allow them to detect objects and perform range finding in order to locate, track and identify targets. Furthermore, motion control systems often use oscillators in order to generate signals for stepper motor movement and control. Finally, communication systems may use oscillators to produce stable clock signals in order to synchronize transmitting and receiving operations carried out in these systems.

Work Principle

8N4QV01LG-0047CDI works on the principle of phase-locked loop. This circuit consists of a Voltage Controlled Oscillator (VCO), a Charge Pump and a Filter. The VCO generates a signal of a frequency controlled by an input voltage. This signal is then passed to the Charge Pump which converts the voltage into current. The Filter separates the noise signals and stabilizes the current, which then goes to the VCO. This current variably adjusts the VCO’s frequency and maintains a stable output frequency under the application of an external input. By providing an external clock signal, the frequency of the output can be controlled precisely.

Conclusion

The 8N4QV01LG-0047CDI is an example of a programmable timer and oscillator. This device is mainly used in various fields such as industrial automation, radar system, motion control, and communication systems. It works on the principle of phase-locked loop and can generate an accurate frequency output in proportion to an input signal provided. It is an ideal choice for applications that require precise control over pulse timing.
