CY2213ZXC-2 Application Field and Working Principle

The CY2213ZXC-2 is a high-precision Frequency Synthesizer Clock Generator and Programmable Divider designed by Cypress Semiconductor. It consists of a low-jitter, frequency-locked loop (FLL) subsystem and two user-programmable divider chains. This product is intended for use in a wide range of applications such as Mobile Networks and Communications, Calculators, Automobiles, Printers, Visual Displays, High-speed Controllers and Timing systems.

Application Field

The CY2213ZXC-2 can be used for a wide range of frequencies and applications. It is suitable for low-power applications, with a Frequency Synthesizer to support frequencies up to 250MHz. It can be used for Mobile Networks and Communications, Calculators and Automobiles, Printers, Visual Displays, High-speed Controllers and Timing systems. The CY2213ZXC-2 is a low-cost solution which is ideal for applications that require precise clock control and precise timing solutions.

The applications of the CY2213ZXC-2 also include wired and wireless communication networks such as 2G, 3G and 4G networks, PC serial host controllers, micro controllers, LC displays, telecommunications, computer peripherals, industrial control and multi-processor systems, automotive protective chassis and audio systems.

Working Principle

The CY2213ZXC-2 consists of a Frequency-Locked Loop Subsystem and two user-programmable divider chains, referred to as Divider1 and Divider2. The FLL Subsystem is composed of a reference time base, a VCO, a phase detector, a charge pump and a loop filter. This is used to generate the desired output frequency. The VCO is tuned by two adjustable registers to provide a wide range of frequencies.

Divider1 provides four user-programmable divide ratios which can be used to divide down the main VCO Output frequency or any other available reference frequency. Divider2 provides only two divide ratios, which are used to divide the output from Divider1. This provides additional flexibility to create more complex frequency dividers. The dividers can be cascaded, provided that the sum of the two dividers is limited to hertz to 4 Hz.

The CY2213ZXC-2 can be programmed for low jitter, wide spread spectrum and large-division frequency synthesis. This speed control loop will operate as frequency synthesizer with low jitter and fast frequency hopping. It also includes manual calibration, allowing the user to program the offset and gain of the VCO, while supporting a wide selection of frequencies.

The main features of the CY2213ZXC-2 include integrated PLL, Digital Divide and Synchronizer, Fast Lock-up Time (Less than 0.2s) and High Frequency Resolution (Down to 1 Hz). It can also support frequency offsets, selectable clock edges, output power sequencing and source sharing. The CY2213ZXC-2 is able to generate precision frequency output and keeps them in sync.

Conclusion

The CY2213ZXC-2 is an ideal solution for applications that require precise clock control and precise timing solutions. It is capable of providing a wide range of frequencies and features and is relatively low-cost. It is suitable for applications such as Mobile Networks and Communications, Calculators and Automobiles, Printers, Visual Displays, High-speed Controllers and Timing systems. The main features include integrated PLL, Digital Divide and Synchronizer, Fast Lock-up Time (Less than 0.2s) and High Frequency Resolution (Down to 1 Hz). The CY2213ZXC-2 is an excellent choice for its feature set and cost benefits.
