Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

CY2077FSXCT is an Applicable Frequency Synthesizer that features a wide range of application fields. The chip is designed with a low-noise, high-integrity, low-skew clock signal generator, and is used in various design applications. It can produce signal output frequencies that range from ultra-fast to audio frequency, and can be used to generate clocks in the high frequency, ultra-wideband and ultra-low-noise range.

CY2077FSXCT is primarily used in clocking applications, such as PC and Ethernet in order to generate high-density multi-rate data. This digital clock generator provides one of the highest clocking accuracy and precision in the market. It is also often used in high-end servers, networking equipments, and storage products. This clock generator is also used for testing in some uncooled thermal imaging applications.

Working Principle of CY2077FSXCT

The working principle behind CY2077FSXCT is based on the concept of a Phase-Locked Loop (PLL), also referred to as a Digital Frequency Synthesizer (DFS). A PLL is a closed-loop of feedback control system which creates a new output signal that is synchronized to the input reference signal.

In a PLL system, a Voltage-Controlled Oscillator (VCO) is used to produce the output signal which is then compared to the reference signal to detect any existing frequency difference. The frequency difference or deviation between the two signals is then used to modify the output of the VCO in order to eventually achieve frequency lock. This synchronization process prevents the output signal from deviating from the input reference signal, thereby improving the performance of the system.

CY2077FSXCT uses a PLL system to generate high-frequency, ultra-low-noise clocks and also five independent oscillators or fanouts. Each of these oscillator or fanout can generate four different output signals with different frequencies, making the chip a true multi-rate clock generator.

The chip operates in two different modes: FM synthesis mode or AM synthesis mode. In FM synthesis mode, the VCO output frequency is multiplied by a pre-defined integer in order to obtain multiple different frequencies. In AM synthesis mode, the VCO output frequency is divided by a pre-defined integer in order to obtain multiple different frequencies.

The CY2077FSXCT chip is designed with a wide supply voltage range from 1.2V to 3.3V, making it suitable for both low-voltage applications and high-end applications.

Applications of CY2077FSXCT

CY2077FSXCT chip frequency synthesizer is often used in some of the following applications:

• Networking and telecommunications.
• High-end servers and storage devices.
• Ethernet and home-networking applications.
