CY7B9940V-2AXCT is a clock generator and phase locked loop (PLL) frequency synthesizer from Cypress. The device integrates a high flexibility, low power PLL and multiple clock output stages into a single package, providing high speed frequency acquisition, precision and noise performance for low power applications. Output signals are highly programmable, including phase offset and duty cycle modes, providing flexibility and reducing system development time.

CY7B9940V-2AXCT operates in two different modes depending on the application requirements. In one mode, the device can produce an output clock signal with a programmable frequency up to 7.2GHz. In the second mode, the system can generate a precise N/N+1 frequency synthesizer with programmable frequency and low power operation. The precision of the clock output is achieved by carefully controlling the oscillator frequency and adjusting the output frequency to the closest integer multiple of the input reference signal. Both modes of operation require the device to be programmed with the desired output frequency, phase offset and duty cycle parameters, using a single serial programming port.

One of the most common application fields of this device is in wireless communication applications, such as cellular phones and wireless local area networks. The device can be used to generate highly precise clock signals to control the transmission and reception of data. Additionally, the CY7B9940V-2AXCT can be used in automotive, aerospace, and other industrial applications. The device has a wide range of clock output frequencies and can be programmed according to the specific requirements of the application.

The operation of the CY7B9940V-2AXCT is based on the principle of phase control. The device utilizes a voltage controlled oscillator (VCO) to generate a clock signal with a frequency dependent on the control voltage. The frequency of the VCO is then compared to the reference frequency, and the difference is used to adjust the control voltage to achieve a desired output frequency. The device is also equipped with a range of features such as jitter-attenuation, system-lock detection and auto load capability, allowing it to be readily integrated into a variety of applications.

In summary, CY7B9940V-2AXCT is a low-leakage, high-performance clock generator and PLL frequency synthesizer. The device is well-suited for use in wireless communication applications and other industrial applications requiring a programmable, highly precise output clock. The device is designed to minimize the power consumption and is programmed with the desired parameters using a single programming port.
