Oscillators

Oscillators are devices extensively used in electronic circuits for generating electrical signals in a wide variety of frequencies. Their applications range from audio and radio frequency communication networks to embedded high speed assemblies. Today, oscillators are extensively used in portable and handheld devices, guided missiles, radar systems, and barcode readers.

Within oscillators, there are two key types: crystals and inductors based circuits. All oscillators, in general, rely upon the properties of either the crystal or the inductor to create an oscillatory circuit. The creation of a continuously oscillating signal is possible due to the balance between the capacitive and inductive components of the circuit.

LFTCXO063710BULK Application Field and Working Principle

The LFTCXO063710BULK is a low-frequency temperature compensated oscillator (TCXO) based on STMicroelectronics\' Multi-Frequency Technology. It is a 15 MHz oscillator device featuring frequency tuning resolution up to 0.05 Hz and total stability up to 10 ppm. Additionally, the device offers features such as low current consumption, wide frequency accuracy and stability range, and low phase noise output.

The LFTCXO063710BULK is ideally suited for use in commercial and consumer applications such as remote control systems, metering systems, and radio links. It has an excellent dynamic response to temperature changes allowing it to be used in a wide variety of applications.

The working principle of the LFTCXO063710BULK is based on the Multi-Frequency Technology (MFT) developed by STMicroelectronics. This technology utilizes two quartz crystals, both resonating at two different frequencies. One of the crystals is used for establishing the output frequency while the other is used for temperature compensation. A frequency counter IC measures the frequency of the output signal which is then compared with the frequency of the reference oscillator crystal. The output frequency is then adjusted accordingly so that the output frequency remains within the specified tolerance values. Additionally, the MFT takes into account the temperature and temperature coefficient of the crystal oscillators to enable temperature compensation.

The LFTCXO063710BULK is a great choice for applications that require reliable frequency accuracy and stability over temperature range. Its low current consumption and wide frequency accuracy and stability range make it suitable for use in portable and handheld devices where high performance is a necessity.
