The CY2547FCT is a fully integrated frequency synthesizer device specifically designed for audio and video frequency synthesis applications. It combines a high performance PLL frequency synthesizer, a high-stability crystal oscillator, and a phase-locked loop (PLL) frequency synthesizer on the same chip. This combination makes the CY2547FCT ideal for audio and video signal generation applications.

A PLL frequency synthesizer typically consists of three basic components: a phase locked loop (PLL), a voltage control oscillator (VCO) and a frequency divider. The PLL locks onto a reference clock signal, typically a highly stable crystal oscillator. The VCO generates a variable frequency output that is “locked” to that of the reference clock. The frequency divider divides this frequency output to the desired frequency.

The CY2547FCT is a PLL frequency synthesizer that provides a fully integrated solution for audio and video signal synthesis. It combines a high performance PLL frequency synthesizer and a high-stability crystal oscillator on the same chip. This combination provides a significantly improved signal-to-noise ratio and jitter performance. In addition, the device is programmable via an I2C interface, allowing for a variety of frequency synthesis configurations.

The CY2547FCT is typically used in video and audio equipment such as television, satellite receivers, audio amplifiers, and video cameras. It is also used in applications such as frequency synthesizers, data communications, and digital signal processing. It is well-suited for digital transmission applications, as the output frequency can be easily programmed to generate a wide range of frequencies.

In addition, the CY2547FCT offers a number of features designed to improve system performance and reliability. These include a wide supply voltage range, programmable up-down frequency counter, auto-calibration, programmable passband (for filtering out unwanted harmonics), and a phase-lock-loop (PLL) phase detector. These features ensure that the device is able to maintain accurate frequency synthesis performance even in challenging conditions.

The CY2547FCT is well-suited for a wide range of applications, including audio and video frequency synthesis, data communications, frequency synthesis, and digital signal processing. Its programmability and robust features make it an ideal choice for a variety of applications.
