The CY28441ZXC is a programmable phase locked loop (PLL) device specifically designed to provide a wide range of frequency synthesis and clock distribution solutions to system designers. It can generate accurately frequency-locked outputs, or output multiple clock and data signals, depending on how it is programmed. CY28441ZXC belongs to Clock/Timing Application Specific.
Clock and timing systems are essential components in today’s electronic systems, providing the foundational element for synchronization and computing across the entire system architecture. The CY28441ZXC is ideal for high-performance applications such as PLL-based clocks, oscillators and digital frequency synthesizers, as well as high-speed PCIe, SAS and PCIe clock sources. It can be used in a variety of internal and external applications that require frequency synthesis, frequency upconversion, frequency locking, clock and data distribution and/or multiple clock frequency output.
CY28441ZXC uses a dual-loop PLL structure with both PLL and frequency synthesizer functions. The PLL is used to lock the frequency of an input signal and generate an accurate output signal. The frequency synthesizer is used to generate multiple output clock frequencies from a single reference input clock frequency. The output frequencies of the PLL and frequency synthesizer are programmable up to 1600 MHz, and its operating voltage range is 3.3 V to 5 V.
The CY28441ZXC includes an on-chip clock generator that allows users to program the device to automatically generate clocks when a reference clock is not available. It also includes an on-chip programmable oscillator that can be programmed to generate clock signals with programmable frequency. The device can also be used with an external oscillator if higher precision or exact frequency is required.
The CY28441ZXC also includes a voltage-controlled oscillator (VCO) and programmable output divider blocks. The VCO is used to generate higher quality signals than can be generated by a fixed-frequency oscillator. It is also used to generate a frequency range from a single input signal and lock it to a reference signal. The output divider block can be used to divide a selected input frequency into multiple output frequencies.
In addition, the CY28441ZXC includes an on-chip phase-frequency detector and charge pump that are used to control the frequency of the VCO. This allows the device to accurately lock the output frequency to the input frequency. The device also includes a digital lock logic block which can detect lock state for the PLL and synthesizer, and provide digital status information.
The CY28441ZXC has a wide range of programming and control options that make it suitable for a variety of applications. It can be programmed to generate a single output frequency from a single input frequency, or generate multiple output frequencies from a single input frequency. It can also be programmed to generate a high-quality, frequency-locked output, or multiple clocks and data outputs for a variety of applications including PCIe, SAS and high-speed PCIe.
Overall, the CY28441ZXC is an ideal solution for designers who need a high-performance, programmable device for frequency synthesis and clock distribution applications. It offers a wide range of features and flexibility that make it suitable for use in a variety of applications.
