Oscillators

Oscillators are electronic circuits that generate and sustain periodic electrical power, or in other words they generate repetitive waveforms, examples being sine wave, square wave, triangular wave, sawtooth wave. The 520M15DA16M3677 oscillator is a voltage-controlled oscillator based on multiple differential amplifier and CMOS divider circuitry that is specially developed for ASIC and SoC applications.

Application Field

The 520M15DA16M3677 oscillator chip is mainly used in ASIC and SoC design for timing synchronization and Clock Generator applications and come in shielded packages for an ultra-small size design. Its low jitter and low power consumption make it suitable for communication and networking components, such as switches, routers, and modems. It is ideal for use in mobile phones, set top boxes, digital cameras, and digital video cameras.

Working Principle

The 520M15DA16M3677 oscillator chip works by using an internal voltage controlled oscillator (VCO) with a frequency range of 1.2 MHz up to 1.6 GHz. It also contains a voltage-controlled ring oscillator (VCRO) and a frequency divider circuit. The VCRO and the frequency divider circuit are two important elements of the 520M15DA16M3677 oscillator chip.The VCRO is mainly responsible for providing the stable frequency. In the VCRO, multiple differential amplifiers are used to create the desired input impedance and gain to ensure that the oscillation remains stable and accurate. The frequency divider circuit then takes this stable frequency and divides it by a user-defined ratio. This ratio is determined using an external control voltage. The output frequency is then determined by multiplying the ratio by the VCRO frequency.

Conclusion

In conclusion, the 520M15DA16M3677 oscillator chip is a voltage controlled oscillator with a wide frequency range, good jitter performance and low power consumption. It is mainly used in ASIC and SoC design for timing synchronization and Clock Generator applications. Its superior features make it suitable for applications in communication and networking components.
