Introduction

The FK3530001 is an oscillator IC designed to create a variety of square and pulse waveforms in order to act as a timebase, PCM encoding or can be used as a clock generator. This oscillator uses a voltage-controlled oscillator (VCO) to achieve a tunable frequency range including several fixed frequency outputs. To generate a suitable output waveform, the IC also includes comparators and output drivers inside the device.

Application Field

The primary application of the FK3530001 is for controlling the frequency of a PCM encoder or a PCM decoder, as the device has a wide range of tunable frequency. For instance, the device can be used to generate frequencies between 64kHz and 833kHz when used as a voltage-controlled oscillator (VCO). When used as a clock generator, the FK3530001 can also be used to generate a range of fixed frequency outputs. In addition to constructing a PCM encoder/decoder or creating a clock generator, the IC can also be used to create pulse-width modulation (PWM) forming a PWM generator, typically used for controlling motor speed or lighting intensity.

Architecture

The FK3530001 contains several sub-circuits such as a voltage-controlled oscillator (VCO), comparators, and output drivers. The VCO is the essential component of the oscillator because it is what allows the user to tune the output frequency to any desired range. The VCO typically operates between the range of 64kHz to 833kHz but its frequency range can be adjusted by either using an external capacitor and/or resistor. The comparator and output drivers are necessary for creating the square waveform output. The comparator takes the signal from the VCO and compares it to an adjustable reference voltage – the comparator then produces a logic output level. The output drivers then distribute the same logic output to multiple gate connections.

Working Principle

The FK3530001 operates using a least switch charge (LSC) method for its voltage-controlled oscillator (VCO). This method works by comparing the input voltage with the voltage at the output voltage of the VCO. The VCO is constructed using an on-board operational amplifier, and then the oscillation process takes place by alternately charging and discharging two external capacitors. The logic output of the comparator is then used by the output drivers to drive out the square waveform signal. The output drivers, similar to the comparator, take the digital logic level generated from the comparator and output it for multiple connection points, therefore the FK3530001 can have various devices connected while all using the same output signal. In addition to a wide range frequency range, the FK3530001 offers excellent accuracy due to its on-board precision components that are used for its VCO. As a result of this, when using either a capacitor and/or resistor to tune the VCO, accurate frequencies can be generated.

Conclusion

The FK3530001 is an oscillator IC designed to create a variety of square and pulse waveforms. The device uses a voltage-controlled oscillator (VCO) to achieve a range from 64kHz and 833kHz as a VCO and a range of fixed frequency outputs when used as a clock generator. The device also includes comparators and output drivers that help it to output the square waveform. The FK3530001 oscillator also offers excellent accuracy due to its on-board precision components used for its VCO. These features make the FK3530001 a suitable choice for constructing a PCM encoder/decoder as well as creating a clock generator or a PWM generator.
