AK8142 application field and working principleThe AK8142 is a low-power voltage-controlled clock generator that supports high-frequency signals for clock generation, PLLs, frequency synthesizers, and signal distributions. It is an ideal product for embedded application which produces frequencies proportional to the applied voltage. The AK8142 is designed with a single-bit differential sigma-delta modulator, a capacitive DAC and a divide-by-N counter. This combination offers accuracy, flexibility, and a wide range of clock output frequencies.The AK8142 is used in a variety of applications, such as PLLs, frequency synthesizers and signal distribution. It is primarily used to generate precise clock signals or to generate two or more precise clock signals with different frequencies. The AK8142 is also used in communication systems and data conversion systems to produce precise clocks for a variety of applications.The working principle of AK8142 is divided into two parts, namely the voltage control and clock output. First, the voltage control is used to control the clock output frequency. The voltage control is achieved by controlling the charge at the capacitor of the on-chip DAC. This charge is converted to a voltage that is applied to the oscillator, and the frequency of the clock output is proportional to the voltage.The clock output is generated by an oscillator and the output is divided by a divide-by-N counter to produce the desired clock frequency. The oscillator frequency is determined by the voltage and the capacitance of the capacitor in the DAC. The divide-by-N counter is used to divide the output of the oscillator to produce the desired clock frequency. The output frequency is determined by the voltage and the clock control register of the DAC. The output of the AK8142 can be used as an input signal for PLLs, frequency synthesizers and signal distributions.The AK8142 is designed to be a low power, high performance clock generator. The power consumption of the AK8142 is only 4 mW when used at 1 MHz. It has an extended temperature range and can operate from -40°C to +125°C. It can also support a wide range of frequencies from 0.1 MHz to 1 GHz.The clock performance of the AK8142 is excellent and it can provide a high output clock accuracy and low jitter. It has a high level of clock output stability and noise immunity. The AK8142 also has excellent crosstalk performance and can support a wide range of input clock frequencies.The AK8142 supports a wide range of programming options and can be programmed via I2C. It can be easily integrated into any system and is compatible with a variety of microcontrollers.In summary, the AK8142 is an ideal product for embedded application which produces frequency proportional to the applied voltage. It is used in many applications, such as clock generation, PLLs, frequency synthesizers and signal distribution. The AK8142 has excellent clock performance and power consumption, making it a perfect choice for a wide range of applications.
