CY2303SXC are highly integrated clock generators and frequency synthesizers designed to simplify clock system design and to improve system performance while minimizing board space. Built with a High Speed CMOS process, they are well suited to applications requiring multiple low skew and low jitter clock sources.

The CY2303SXC has twelve differential outputs, each of which can be configured for either LVDS (Low Voltage Differential Signaling) or LVPECL (Low Voltage Positive-Edge Clock Logic) with clock frequencies from 250 MHz up to 500 MHz. The device features an input PLL (Phase Locked Loop), a voltage controlled oscillator (VCO) and a jitter cleaner circuit for optimal clock performance.

The application field for this integrated master clock generator includes PC systems, Networking Equipment, Storage Devices, and Event Timers. It is also used for System Clock Generation and Distribution, Clock Synthesis and Phase Locked Loop Clock Generation.

The working principle of the device is based on the concept of a PLL. Basically, the PLL provides a method of generating and controlling a signal, typically a clock signal, whose frequency and phase characteristics can be dynamically changed as required. This signal, the VCO output, is then conditioned and output, most often in the form of an all digital clocks and symbol timing signals, providing the necessary timing interface for digital systems.

The CY2303SXC is designed to simplify clock layouts while meeting the stringent timing requirements of today’s systems. Its capabilities, from low skew and low jitter outputs, allow for minimal board area, high output frequencies and low power consumption.

The device operates using a wide spread of external control signals. An input control signal is applied to the device, instructions are then followed, and clock outputs are sent to their respective loads. The CY2303SXC offers up to twelve outputs that are either Low Voltage Differential Signaling (LVDS) or Low Voltage Positive-Edge Clock Logic (LVPECL).

The device features an output divider that allows the user to specify a divider ratio, which is used to generate a signal frequency of up to 500 MHz. The device also has a jitter cleaner circuit, which eliminates clock signal jitter, making it suitable for high performance digital signal processing applications. In addition, the device has jitter attenuation and clock output skew controls, which allow the user to adjust the phase and timing characteristics of the clock signals.

Overall, the CY2303SXC is a highly effective and efficient clock generator and frequency synthesizer designed to simplify clock system design while improving system performance while minimizing board space. The device has twelve differential outputs, is able to generate frequencies up to 500 MHz, features a jitter cleaner circuit, and has low skew and jitter outputs. It is well suited for PC systems, Networking Equipment, Storage Devices, and Event Timers as well as for System Clock Generation and Distribution, Clock Synthesis and Phase Locked Loop Clock Generation.
