CY28RS480ZXCT Application Field and Working Principle

Clock/Timing - Application SpecificThe CY28RS480ZXCT is a high-performance, low-cost clock synthesizer designed for distributed clock systems. It features a wide selection of input frequencies, an adjustable output frequency, and an adjustable clock skew. With its low cost and high performance, the CY28RS480ZXCT is the ideal choice for applications that require precise timing synchronization across distributed systems.The CY28RS480ZXCT is based on Programmable Clock Synthesis (PCS) technology, which allows for comprehensive adjustment of the clock output frequency and skew. PCS is a powerful technology that provides a great deal of flexibility in generating a wide range of output frequencies, as well as high precision in clock timing. With PCS, the CY28RS480ZXCT can generate highly precise min/max output delays, allowing designers to achieve tight synchronization in advanced timing applications. The CY28RS480ZXCT is a versatile solution for various applications. It can be used in servers and storage systems to synchronize data access, network traffic, and other timing-related components. It can also be used in medical systems and embedded systems to ensure accurate timing of critical operations. Furthermore, the CY28RS480ZXCT is used in industrial automation to enable critical timing of motion control systems.The CY28RS480ZXCT features a wide range of adjustable parameters for fine-tuning the clock output frequency and skew. The available parameters include the input selection, input load, different register outputs, and a wide selection of VCO frequencies.The CY28RS480ZXCT uses a PLL (Phase Locked Loop) to lock the output clock to the input reference clock. The VCO output is fed back to the PLL and compared to the input reference clock. When the compared signals match, the PLL is said to be in a “lock” state. The lock state is maintained as long as the PLL control loop is unperturbed.The output of the PLL is a “locked” clock signal, which is then sent out to the user-specified output frequency. The CY28RS480ZXCT also features adjustable output skew, making it possible to compensate for long-distance transmission losses, jitter, and other factors that may degrade the output frequency. The clock output of the CY28RS480ZXCT is also programmable, allowing users to specify the frequency, duty cycle, phase, and skew. The programmable parameters can be adjusted using the integrated I2C controller, or via the optional serial interface.In summary, the CY28RS480ZXCT is an ideal choice for applications that require precise clock synchronization, as it provides a wide selection of frequency and skew adjustments, as well as programmability for more advanced requirements. Its low cost and high performance make it a great value for many distributed clock applications.
