Oscillators

The 520M25IT13M0000000 is a type of oscillator, an electronic circuit with an output signal that vibrates or cycles between two states, normally a high and a low level. In electronic engineering, oscillators are used to generate signals for other circuits, such as timers and frequency detectors. Frequency is the number of times the waveform cycles per second, so in oscillators, a frequency is specified for how often it should oscillate. It can be a simple square wave or a more complicated waveform.

Specifications

The 520M25IT13M0000 is a 14-pin 0.9mm SMD (Surface Mounted Device) oscillator that operates at a frequency of 5.25MHz to 25MHz. It is available in a range of frequency tolerance and operating temperature variations, ranging from±1% to ±50% tolerance, and a temperature range of -40°C to +85°C. It is supplied with TTL or CMOS compatible along with with output buffering.

Application Field

The 520M25IT13M0000 oscillator can be used in many applications, such as frequency synthesizers, spread spectrum communications, keyless entry systems, car security systems, wireless LAN systems, CCD camera modules, DVD and CD players, HDTV systems, modems, fax machines, and PCS systems. It can also be used for timing devices such as watches, clocks, and other electronics.

Working Principle

The 520M25IT13M0000 is a voltage-controlled oscillator, which means that it oscillates at a frequency that is determined by the voltage applied to its control electrodes. Its oscillation frequency is determined by the amount of current applied to its control electrodes, and the output voltage is a function of the frequency applied across its input terminals.

The 520M25IT13M0000 can be configured in positive or negative gate mode. In negative gate mode, the applied voltage increases the gate voltage, resulting in a decrease in current flow and a corresponding decrease in oscillation frequency. In contrast, a positive gate mode increases the gate voltage when a positive voltage is applied, causing an increase in current flow and a corresponding increase in oscillation frequency.

The 520M25IT13M0000 works on a principle known as feedback, or negative feedback. It works by applying an input signal with a specific frequency to one of its electrodes, and the output of the device is fed back to the other electrode, creating an oscillatory current flow in its circuit. This oscillatory current creates a feedback loop, generating a steady-state signal at a certain frequency, according to the parameters of the device.

The 520M25IT13M0000 oscillator is a highly reliable device, as it is composed of an integrated circuit and an external quartz crystal. The design of the device ensures that it can withstand harsh conditions, such as extreme temperature, vibration, and mechanical shock. This makes it an ideal choice for applications requiring high levels of reliability.
