The CY2308ESXC-2 is an advanced clock chip for clock/timing applications that provides excellent frequency accuracy and low jitter performance. This product is ideal for places where clock accuracy and precision are essential. It is a highly integrated, cost-effective clock module that offers five selectable clock frequencies and is designed to meet the requirements of communications, precision measurement, industrial, and consumer electronics applications.

In clock/timing applications, the CY2308ESXC-2 works by generating a high-accuracy reference clock signal through a frequency synthesizer. This reference clock is then used as the source of all system clock timing signals. In this way, it can serve as a master clock for the rest of the system by generating the reference clocks for peripheral components and CPUs such as microprocessors and memories.

The CY2308ESXC-2 features an on-chip PLL, which provides tight jitter specification and wide frequency coverage to ensure high frequency accuracy and precision. The PLL can be used to either generate clock frequencies that are close to the reference clock, or to synthesize a wide range of frequencies from the reference clock. The PLL can also be used to generate a digital version of the reference clock signal.

The CY2308ESXC-2 also features a low power sleep mode and a low jitter suspend mode that helps to reduce overall power consumption. In addition, the chip offers an adjustable impedance that can be used to adjust the output signal for better clock synthesis accuracy. This on-chip adjustable impedance allows for the tuning of the output signal for better frequency accuracy. This feature is a major benefit for those applications needing to meet specific or stringent reference clock accuracy requirements.

The CY2308ESXC-2 also offers an optional spread spectrum reference clock signal for improved noise immunity and reduced EMI. This feature also helps to reduce system cost by eliminating the need for external shielding and noise suppression components.

The CY2308ESXC-2 is available in both a five and six-output version. The five-output version provides the required clock speeds while the six-output version offers an additional clock signal, which is dedicated to PLL and CPU synchronization. This clock signal ensures that the system timing signals are in synchronization with the CPU and other peripherals, reducing overall system signal jitter.

Overall, the CY2308ESXC-2 is a cost-effective, highly integrated, and reliable clock chip for a wide range of clock/timing applications. It offers excellent frequency accuracy, low jitter performance, and optional spread spectrum reference clock signal support. It also provides the necessary power management features and adjustable impedance to ensure system cost savings. As such, it is an ideal choice for precision measurement, communications, industrial, and consumer electronics applications.
