FT801Q-T is a widely used voltage-controlled oscillator (VCO) which is mainly used for linear video processing. It is designed for Pulse Width Modulation (PWM) applications such as TV broadcasting and other commercial audio and video applications. The FT801Q-T VCO provides a robust frequency output with low noise and distortion in a very small package size.

The FT801Q-T VCO is based on an integrated circuit containing a voltage-to-frequency converter (VFC) and a conventional oscillator, with a minimum of external components. The VCL has a wide frequency range from 0.2 Hz to 40 MHz and a minimum input voltage range from 0.3V to +5V. The output frequency is linearly related to the input voltage and is adjustable using either the control voltage or an external capacitor. Its high output linearity, low distortion and high resolution make FT801Q-T an ideal choice for linear video processing applications.

The working principle of FT801Q-T is based on the principle of a voltage-controlled oscillator. The VCO consists of two basic components, the voltage-to-frequency (VFC) converter and the oscillator circuit. The VFC converter takes the input voltage, which can vary over a wide range, and converts it into a frequency which produces a linear output voltage. This frequency is then fed into the oscillator which is an LC circuit. The oscillator circuit is used to maintain a stable output frequency. The oscillators frequency is determined by the VFC output and is adjusted by the control voltage. The output voltage from the VCO is then sent to the video processing logic which is used to convert the analog video signal into digital video format.

The FT801Q-T VCO is an excellent choice for linear video processing due to its wide frequency range, high output linearity, low distortion and high resolution. It is also relatively easy to use, as it requires no additional components and has a wide operating range. The FT801Q-T also provides a reliable and cost-effective solution for broadcast and commercial audio-video applications.
