Oscillators

An oscillator is a device or circuit that creates an oscillating signal — a signal that rises and falls in amplitude with a certain frequency. Such oscillators are used to create and shape electric signals often in the radio frequency range. Oscillators are key building blocks in electronic systems and devices, and they are used in almost every field of technology.

The 653E156H3C2T oscillator is a programmable dual frequency oscillator that operates on either the 4.5V or 3.3V range. Operating at a temperature range of -20°C to 70°C, it is designed to be part of a system control circuit, providing a signal to drive logic and providing synchronization to other clock related devices. This oscillator can support a wide range of frequencies, ranging from 10MHz to 50MHz and featuring programmable frequencies of 1, 2, 12, 13, 14, 15, 25, 29 and 30 MHz.

The 653E156H3C2T oscillator also features dual output signals – either low voltage differential signaling (LVDS) or clock multiplier output (CMO) – enabling it to work with a variety of different logic systems. The CMO signal can be programmed to output a signal that is as low as 10MHz and as high as 50MHz, making it ideal for use with various logic systems that require a wide range of frequencies.

Working Principle

The 653E156H3C2T oscillator works on a basic principle known as the Colpitts Oscillator. This is a type of electronic oscillator circuit that uses two capacitors and an inductor to produce an oscillating electrical signal. The principal components of the Colpitts oscillator are the transistor, bias resistor, two variable capacitors (forming a divider) and an inductor. The oscillation is generated by the negative feedback between the two capacitors.

One of the capacitors (known as the feedback capacitor) acts as a feedback element, sending the output signal back to the transistor. This causes the circuit to change state, going from an on-state (amplifying the signal) to an off-state (shutting off the signal). The positive side of the capacitor is kept at a set potential (this is known as the bias state) so that the transistor has a reference point. The capacitor then alternates between the two states, toggling the conduction of the transistors and creating an oscillating signal.

The second capacitor (known as the reference capacitor) acts as a voltage divider, providing a constant reference voltage to the transistor. This allows the transistor to switch between the two states quickly and efficiently. The inductor, meanwhile, helps to maintain the oscillation (by providing additional electrical energy to the circuit) and increases the circuit’s stability. The 653E156H3C2T oscillator is based on this same principle.
