CY28401OXC is an advanced low power PLLs (phase-locked-loops) designed to provide an optimal solution for frequencies ranging from 10 MHz to 400 MHz. Operated at 3.3V digital voltage, this device contains two independent phase frequency detectors, two charge-pump current sources and two low power oscillators. It also straps a digital loop filter and provides an output divider. That makes this device ideal to achieve low phase noise and fast frequency lock-in times.

The CY28401OXC is the ideal choice for use in high-powered applications such as those in communications equipment and for applications that require high data rates. The device is also suited to applications in which high levels of power dissipation is of concern, such as in battery-powered systems. It can also be used in mission critical systems in order to reduce system down-time caused by component failures.

The CY28401OXC is ideal for use in frequency synthesis, timing extraction, and clocking operations. It can be used in a wide variety of applications where very accurate timing and frequency control is essential, such as in communications and timing recovery systems.

The working principle of the CY28401OXC is based on the concept of locking the phase and frequency relationships between two signals. The device contains twooscillators that generate two input signals with one being the reference and the other being the feedback signal. The phase and frequency detectors compare the phase difference between the two signals and generate a control signal that is used by the charge pump to maintain the phase and frequency relationship between the signals

The CY28401OXC operates by employing a digital loop filter which is used to filter changes in the control signal provided by the phase frequency detector. The filtered signals are used to control the charge pump current sources to provide an output voltage to the oscillators that compensates for changes in the frequency or phase. The oscillators are then adjusted until the phase and frequency are in a stable relationship. The output divider can be used to adjust the output frequency so that it matches the reference frequency.

The CY28401OXC can be used in a variety of applications to provide the specified data rates, synchronization, and even timing extraction. In addition, the device can be used in applications that require accurate frequency and timing control, such as communications and timing recovery. In these applications, the device can offer excellent performance in terms of frequency jitter, cycle-to-cycle accuracy, and power consumption.

In summary, the CY28401OXC is a high-performance, low power PLL device that can be used in a wide variety of applications. The device is ideal for use in frequency synthesis, timing extraction, and clocking operations. It can be used to provide stable and accurate frequencies and timing from 10 MHz to 400 MHz. It is also suited for applications where a high degree of frequency stability and accuracy is required. Furthermore, the device is capable of providing excellent performance in terms of frequency jitter, cycle-to-cycle accuracy and power consumption.
