The CY2077FSXC is a single-chip frequency synthesizer from Cypress Semiconductor. It is an advanced, low-cost device that utilizes Sinusoidal Pulsewidth Modulation (SPWM) for frequency synthesis, making it ideal for consumer and embedded applications where precise frequency control is desired. The CY2077FSXC is often used in automotive, industrial, and consumer applications in which frequency control is needed, such as for clocks and sound controllers.The CY2077FSXC uses a range of digital and analog design techniques to provide superior performance and flexibility. The device consists of a dual-channel frequency synthesizer and a single-channel PLL-based frequency synthesizer. The dual-channel frequency synthesizer allows users to program up to 20 different frequencies, while the PLL-based frequency synthesizer lets users program up to eight different frequencies. The dual-channel frequency synthesizer is capable of producing frequency resolutions down to 0.001 Hz, which is a very small step size that is often needed in consumer applications.The CY2077FSXC utilizes a closed-loop fractional division technique to provide frequency synthesis. This technique allows users to set frequency synthesizer output frequencies very accurately. The device supports output powers ranging from 5 to 25 milliwatts, which is suitable for most consumer applications. Additionally, the device supports frequencies of up to 300 MHz, making it ideal for consumer applications such as clock sources and sound controllers.The CY2077FSXC also provides several additional features, including power fail protection, temperature-compensated reference frequency output (TCRFO), and temperature-compensated oscillator (TCO). These features provide enhanced performance and reliability for the device. Additionally, the device supports two independent PLLs and two output ports, allowing users to build complex frequency synthesizer applications.To control the frequency synthesizer, the CY2077FSXC employs a SPI-compatible interface. This interface allows users to easily configure the device and its settings. The device also incorporates several features to help increase the overall system performance, such as synchronous start-up, a power-down freeze mode, and a clock-lock monitor. In summary, the CY2077FSXC is a low-cost, high-performance frequency synthesizer device that utilizes Sinusoidal Pulsewidth Modulation (SPWM) for frequency synthesis. Its dual-channel frequency synthesizer allows users to program up to 20 different frequencies, while the PLL-based frequency synthesizer lets users program up to eight different frequencies. The device supports frequencies of up to 300 MHz, and incorporates several features that help increase the overall system performance, such as synchronous start-up and a power-down freeze mode. Additionally, the device includes power fail protection, temperature-compensated reference frequency output (TCRFO), and temperature-compensated oscillator (TCO). All these factors make the CY2077FSXC an ideal device for consumer and embedded applications where precise frequency control is desired.
