Design Considerations When Using 8N4DV85FC-0144CDI8

When designing with the 8N4DV85FC-0144CDI8, careful consideration should be given to the application\'s system-level requirements. Designers must consider the timing accuracy required, the levels of jitter, noise, voltage levels and temperature ratings. The 8N4DV85FC-0144CDI8 implementation allows up to sixteen individually-configurable frequency selections, which can be set by programming the device using serial registers.

Working Principle of 8N4DV85FC-0144CDI8

The 8N4DV85FC-0144CDI8 utilizes an oscillator to generate a clock signal with a frequency equal to the desired output. The oscillator is then connected to a multiplier circuit and voltage controlled oscillator, which is programmed to set the frequency and the fractional multiplication ratio. During the design process, a proper program is used to ensure that the desired output frequency is produced with the specified accuracy and stability. The 8N4DV85FC-0144CDI8 is then programmable with a serial communication interface to select the desired frequency and fractional multiplication ratio. This will set the clock/timing generator to produce the desired clock output with minimal jitter, noise and power consumption.

Conclusion

The 8N4DV85FC-0144CDI8 Programmable Timers and Oscillators product is an ideal option for SOC, mobile and consumer applications. It provides improved accuracy and flexible configuration options while still offering a low total power consumption. The device can be programmed using a serial communication interface to allow the user to select the desired frequency and fractional multiplication ratio. With careful design considerations, the 8N4DV85FC-0144CDI8 can be used to produce the desired clock output with minimal jitter, noise and power consumption.
