CY25560SXC is a flexible clock generator and frequency synthesizer, designed to generate multiple low power and low noise digital clock signals. It is a highly integrated CMOS device which includes programmable reference clock receiver, VCO, PLL control logic, crystal oscillator driver and output buffer.The main application fields of CY25560SXC chip involve clock generators, flexible frequency synthesizers and plug-in transceivers. It can generate multiple low-jitter clock signals with programmable frequencies, enabling the ideal interface for links over 25Gbps and next-generation protocols over 56Gbps.The working principle of CY25560SXC can be divided into four stages: clock input, Clock Multiplier, Phase Frequency Detector (PFD), and the Voltage-Controlled Oscillator (VCO). First, the chip receives clock input from external or internal clock source or reference frequency, or differential clock inputs. It then processes the input clock frequency signals and passes it to Clock Multiplier (also known as Clock Divider). The chip acts as a frequency divider and clock differential and symmetrical cross- point buffers are used to divide and transfer the signals to the PFD. The feedback signals from the PFD are compared and their phase differences are calculated. A low pass filter (also known as Loop Filter) is then used to generate corrective DC-level that is used to adjust the voltage gain of the VCO. Finally, an output buffer is used to convert the output of the VCO into desired clock frequencies. CY25560SXC chip is advantageous due to its low power requirement with 1.2V typical supply voltage and 68-mA typical current supply specification. The chip also offers flexibility in system design due to its programmable reference and clock inputs, adjustable output termination and output configuration options. Its low jitter performance is also excellent while providing a maximum frequency of 250MHz (CW). It is also beneficial to use CY25560SXC chip as there is no requirement for on-chip or external crystals and its PLL feedback loop allows for excellent phase locking accuracy performance. The chip is also shock and vibration tolerant and does not require lengthy lock and wait times which simplifies the design process. As the chip is highly flexible and has several advantages, it is becoming increasingly popular in the industrial area. From networking applications such as plug-in transceivers and flexible frequency synthesizers, to embedded applications such as clock generators with embedded frequency settings, communication applications and other industrial applications involving reliable transmission technologies, the CY25560SXC chip is a perfect choice for all. Moreover, the CY25560SXC chip family supports a variety of clock outputs, including differential outputs, single-ended outputs, and dual-clock outputs. The chip can also provide four independent outputs, up to 132MHz and up to four banks of programmable duty cycles. It also supports multiple clock inputs and can generate frequencies up to 250MHz (CW). In conclusion, the CY25560SXC chip offers an excellent and create solution for clock generation and frequency synthesis. It is easy to integrate with existing systems, provides low power consumption and a long lifetime. Its low jitter performance and wide frequency range make it an ideal choice for industrial applications.
