Oscillators

Oscillators are self-sustained electronic circuits that generate a continuous periodic electrical signal. These signals are widely used in providing a wide variety of functions, including signal timing, synchronization, frequency division, etc. This article will discuss the application field and working principle of SG-710ECK 6.1440MB oscillator.

Application Field of SG-710ECK 6.1440MB Oscillator

SG-710ECK 6.1440MB oscillator is mainly used in consumer electronic products, such as digital cameras, digital video cameras, Handycam, mobile phones, PDAs, Bluetooth systems, etc. It is also used in medical devices, automotive systems, GPS receivers, and wireless communication systems.

Its wide-spread application can be attributed to its low profile and small size. Moreover, because of its superior performance, it is well known for producing low jitter signals, which makes it suitable for high-speed digital applications. This oscillator can also be used to replace quartz crystals, as it operates at a low power rate and generates a low noise signal.

Working Principle of SG-710ECK 6.1440MB Oscillator

SG-710ECK 6.1440MB oscillator works on the principle of frequency-backwarding, and generates signals in a frequency range of 6.1440MHz. In its working process, it transfers the signal frequency, from the close-loop frequency-network to one of the pins.

This oscillator works in a two-stage architecture, consisting of a phase-locked-loop (PLL) and a frequency-locked-loop (FLL). A master oscillator, which works in a self-oscillation mode, and a programmable frequency divider, are the two components of the PLL stage. This master oscillator generates the base frequency, and the programmable frequency divider is used for changing the frequency value. This value is set to the desired frequency, by externally setting the phase and frequency of the oscillator.

The second stage is the FLL stage, which consists of a digital loop filter, analog loop filter, and phase comparator. The phase comparator provides the comparison between the two adjustable frequencies and produces an error signal. This error signal passes through the analog loop filter, and after some calculations, it is sent as a frequency correction signal to the programmable frequency divider.

The frequency-correction signal produces the desired output frequency, and the output frequency and phase are adjusted according to the input conditions. This output frequency is then passed through the digital loop filter, which ensures the stability of the frequency and phase at the output. This feedback loop provides the correct frequency and phase information, and helps to regulate the oscillator.
