Oscillators

TCO-7087X1A4 8.0000M is an oscillator designed for applications that are in need of precise, high accuracy frequency stability and short start-up times for reliable, continuous performance over a temperature range of -40ºC to +85ºC. Its application range is wide and its working principle is based on the utilization of a quartz crystal resonator.

This oscillator is built on the latest high-performance ASIC technology which adds rock-solid jitter performance to the device. The operating principle of the oscillator is quite simple. It works on the following three principles:

• It utilizes a quartz crystal resonator to control the frequency of the oscillations.
• It uses a Voltage-Controlled Oscillator (VCO) to control the frequency of the oscillations.
• It uses a Phase-Locked Loop (PLL) to regulate the frequency of the oscillations.

The quartz crystal resonator is the fundamental part of the oscillator. It modulates and controls the frequency of the oscillations by adjusting the voltage of the resonator. The resonator is used to convert electrical energy into mechanical energy according to the quartz crystal properties. The quartz crystal is a natural crystal material which has low impedance and a very stable frequency response over a wide temperature range, allowing for precise frequency regulation and a very low phase noise.

The VCO is a type of oscillator which is used to control the frequency of the oscillations. The oscillator takes input frequency from the quartz crystal resonator and produces an output frequency by adjusting the voltage of the VCO. The output frequency of the VCO can be controlled using a microcontroller, which allows for precise frequency regulation within the oscillator’s specified range.

The Phase-Locked Loop (PLL) is a type of feedback mechanism which is used to maintain stability within the oscillator. The PLL uses the sinusoidal waveform generated by the quartz crystal resonator and compares it to the VCO output frequency. If there is a discrepancy between the two frequencies, the PLL adjusts the output frequency of the VCO so that they match.

TCO-7087X1A4 8.0000M oscillator is designed for a broad range of applications including microprocessor-based systems, industrial automation, satellite navigation receivers, microwave test and measurement, telecom, and communications, and medical equipment. The oscillator offers an 8Mhz output frequency, low power consumption, low start-up time, and excellent short-term and long-term frequency stability over the full operating temperature range of -40ºC to +85ºC.
