4P143F35IST Application Field and Working Principle

4P143F35IST is an integrated circuit (IC) designed for the field of crystal-controlled analog systems. It is capable of detecting, controlling, and switching voltages in order to initiate the oscillation of quartz crystals. It is used in applications such as oscillators, amplifiers, waveform generators, and frequency multipliers.

The device consists of two main components: the oscillator circuit and the control circuit. The oscillator circuit contains two configured quartz crystals, a feedback capacitor and resistor, and two transistors. The transistors are used to amplify or dampen the oscillations from the crystals. The control circuit contains a voltage input terminal and two control connections. The voltage input terminal is used to monitor the output of the oscillator circuit and adjust the output accordingly. The control connections are used to adjust the frequencies of the connected crystals.

Oscillator Circuit

The two quartz crystals work together to create an oscillation frequency. This frequency depends on the size of the quartz crystals and the type of electrical field they experience. The feedback resistor and capacitor are used to reduce the amount of energy lost by the oscillation process and increase the frequency stability.

The two transistors act as amplifiers or dampeners in order to create the desired frequency. This is accomplished by controlling the voltage going into the crystals. If the voltage is increased, the transistors will act as amplifiers and the frequency will increase. If the voltage is decreased, the transistors will act as dampeners and the frequency will decrease.

Control Circuit

The control circuit is used to monitor the output of the oscillator circuit and adjust the voltages going into the crystals. This is done by monitoring the voltage at the input terminal and using the two control connections to adjust the voltages accordingly. The control connections are used to adjust the frequencies of the connected quartz crystals.
