Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The CY2308SI-1H is an integrated programmable oscillator with frequency range from 2 to 140 MHz and is designed to provide timing solutions which require a wide range of precision and flexibility. It uses a high-performance silicon MEMS Resonator to generate a base frequency, then the output frequency can be freely adjusted by a three-state through the seven resistors of the CY2308SI-1H.

Application

The main application fields of the CY2308SI-1H are mobile communication and consumer electronics. The mobile communication has a rapidly increasing data rate requirement, and it requires reliable clock to ensure the accuracy of mobile communication, so the CY2308SI-1H can be used for frequency synthesizing of mobile and wireless communication systems.

Another application field is consumer electronics. CE products operate in high frequency and need to runs faster and more reliable. Because of the CY2308SI-1H\'s wide range frequency output, high jitter and stability performance, it can be used for clock synchronization system in consumer electronics products.

Working Principle

The core of the CY2308SI-1H is a high-performance silicon MEMS Resonator and an internal circuit for frequency tuning. The resonator is a vibrating structure whose inherent frequency and amplitude are dependent on the intrinsic mechanical parameters. The resonant frequency is determined by the length and width of the device, plus the tensile stress on the device itself and the substrate.

The resonator generates a base frequency, then it\'s fed into the control circuit inside the device, where it goes through a frequency divider loop. The outputs of the loop are shaped, amplified, filtered and sent to the output. The output frequency can be adjusted by seven resistors inside the CY2308SI-1H. The output frequency of the CY2308SI-1H can be tuned by -100ppm to +100ppm in steps of 1ppm.

System Design Consideration

When designing a CY2308SI-1H system, consideration should be given to matching between device\'s physical connection and the system\'s electrical parameters, such as voltage, timings, operating environment, etc. The electrical parameters must be matched to the device for reliable performance.

  • Operating Voltage: The device\'s rated voltage should be matched with the system\'s voltage. It should be noted that some devices also require an external clock source. If the device requires an external clock source, the external clock source should be checked for compatibility.
  • Timings: The device\'s performance is temperature dependent, so the timings should be selected to match the temperatures likely to be encountered in the system.
  • Operating Environment: The operating environment should be checked to make sure that it is suitable for the device. The CY2308SI-1H is designed to operate in temperatures up to 85°C. If the device is to be used in an environment with a higher temperature, cooling measures should be taken.

Conclusion

The CY2308SI-1H is a high-performance integrated programmable oscillator for timing solutions which require a wide range of precision and flexibility. It is mainly used in the mobile communication and consumer electronics field. The output frequency can be adjusted from 2 to 140MHz in steps of 1ppm. When designing a CY2308SI-1H system, consideration should be given to the electrical parameters, operating voltage, timings and operating environment to ensure reliable operation.
