The SN74LV4046APWRG4 is a monolithic Clock Generator and Frequency Divider circuit designed for high data rate applications. It is available in plastic DIP and TSOP packages. The SN74LV4046APWRG4 can be used for generation of sine wave clocks in the range of 1Hz – 2MHz and for frequency division from 0 (DC) to 2MHz. The frequency is adjustable by three external resistor and capacitor components, typically within 0.1% accuracy.
Application Field
The broad application field of the SN74LV4046APWRG4 covers a wide range of frequency generation and division. Uses include frequency translation, clock synthesis, bit-rate translation and clocking of logic gates. The device is especially suitable for digital signal processing, communication devices and in switching power supplies where high frequency clock sources are required. It can also be used for the generation of low frequency digital signaling in low power applications.Working Principle
At the heart of the SN74LV4046APWRG4 is a voltage-controlled oscillator (VCO) with a divide by-3 frequency divider chain. The VCO output is divided by one of 3 different stages to generate the final frequency output. The SN74LV4046APWRG4 has an external switchable frequency selection input, which allows the user to choose between two different frequencies. The output frequency can be adjusted with three external resistors and two external capacitors.The SN74LV4046APWRG4 has two selectable output frequencies: a high frequency (HFO) and a low frequency (LFO). The HFO has a preset frequency range of 1Hz to 2MHz, while the LFO has a preset frequency range of 16.5Hz to 215Hz. The HFO frequency can be adjusted with three resistors (R1, R2 and R3), while the LFO frequency is set by two external capacitors (C1 and C2).The external clock input is used to synchronize the operation of the oscillator. A logic “0” signal on this pin will force the oscillator to reset, while a logic “1” signal will cause the oscillator to start up again. This feature allows the SN74LV4046APWRG4 to work as a frequency generator or frequency divider.Conclusion
As an ideal clock generator and frequency divider, SN74LV4046APWRG4 is suitable for various applications, such as frequency translation, clock synthesis, bit-rate translation and clocking of logic gates. It will play an important role in digital signal processing, communication devices and in switching power supplies.The specific data is subject to PDF, and the above content is for reference
