Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The CY2XL11ZXCT is an advanced clock generator and frequency synthesizer device from Cypress Semiconductor. This intelligent timing solution provides a programmable interface to generate different signal clock signals and frequencies while maintaining tight accuracy. The CY2XL11ZXCT is ideal for consumer, industrial and medical products requiring precise synchronization and timing performance.

Application Fields

The CY2XL11ZXCT’s versatile designs, compact and low profile package makes it ideal for many applications. These include PCs and servers, optical data transfer and storage, server-side and cloud computing, high-performance gaming consoles, medical systems and high power radio frequency applications.Besides high precision timing and frequency control, four adjustable output voltage levels (1.2V, 1.8V, 2.5V and 3.3V) enable the device to be optimized for different voltage swing requirements in applications where low-jitter is critical.

Working Principle

The CY2XL11ZXCT follows the traditional StrataClock frequency synthesis architecture. It consists of an on-chip digital PLL (Phase-Locked Loop) with two main elements: a synthesizer, which generates a given frequency using a programmable frequency control word (FCW) and reference crystal; and a Frequency Locked Loop (FLL), which adjusts the frequency generated by the synthesizer to match the given reference frequency.The on-chip PLL unlock detector also monitors the PLL to ensure proper lock at the desired frequency. In the event of an unlocked condition, the device outputs an unlock signal to notify the system of a state change.The device also features an integrated Direct Digital Synthesis (DDS) block to provide precise frequency control and programmable output frequencies. The use of the DDS allows the output frequency to be programmed over an extended range with greater accuracy than the traditional frequency synthesis techniques.In addition, the CY2XL11ZXCT also supports Spread Spectrum Clocking (SSC), reducing Electromagnetic Interference (EMI) within electronic systems. This enables the device to operate in higher density environments and reduces the risk of interference from other sources.Finally, the strong jitter performance achieved by the CY2XL11ZXCT enables precise synchronization between different devices. This feature lets clock signals, frequencies and timing data to be transferred and managed with high accuracy.

Conclusion

The CY2XL11ZXCT from Cypress Semiconductor is a highly integrated clock generator and frequency synthesizer that is compact and offers advanced timing features. The device offers precise timestamp and frequency control, as well as programmable output voltage levels and Spread Spectrum Clocking. It is suitable for a wide range of clock signal and frequency applications in consumer, industrial and medical systems.
