Oscillators are devices that emit a periodic signal with a given frequency. The frequency of the oscillator can come from a quartz crystal, a temperature-sensitive resistor, or a circuit design found in an integrated circuit. The TCO-7087X1A 20.0000M0 is a high-frequency oven-controlled crystal oscillator (OCXO), which is known for its high-precision and long-term stability.
The TCO-7087X1A 20.0000M0 is suitable for many applications such as frequency control in broadcast systems, communications systems, precision measurements, radio networks, test-and-measurement systems, and satellite communications. It is designed to provide stable reference frequencies for circuits from 10 MHz to 110 MHz.
The TCO-7087X1A 20.0000M0 is constructed as a complete package that includes a crystal resonator, an oscillator circuit, a pre-amplifier, and an amplifier. The operational frequency of the TCO-7087X1A 20.0000M0 is 20.0000MHz, which is also its center frequency accuracy specification. The frequency stability is +0.05 ppb over the entire temperature range of +0 to +50°C. The phase noise is -120dBc/Hz at 100kHz offset from carrier. The specified holdover stability is +0.5 ppb over the temperature range of +25°C to +50°C for 30 days. The clock input voltage range is 2.5 VDC to 3.3 VDC.
The TCO-7087X1A 20.0000M0 uses a crystal oscillator, an amplifier, and an oven to maintain its stability and accuracy. The oscillator is a quartz crystal that vibrates to a certain frequency depending on its mechanical characteristics. This vibrating crystal is surrounded by a heating element, which is controlled by a feedback loop which maintains the crystal at a precise temperature. This temperature-controlled oscillator, called an oven-controlled oscillator is more stable than a quartz oscillator, and is better able to compensate for temperature variations, which makes it suitable for precision applications.
The oscillator circuit of the TCO-7087X1A 20.0000M0 amplifies the output of the crystal so that it is capable of providing a larger signal. The pre-amplified signal from the crystal oscillator is then amplified by an amplifier. This amplified signal is then used to drive the clock output. The oven-controlled crystal oscillator provides a precise reference frequency that is used to synchronize other oscillators. The output signal of the oscillator is a square wave pulse, which can be used to synchronize circuits that require a precise timing reference.
The TCO-7087X1A 20.0000M0 is a high-precision, oven-controlled quartz crystal oscillator that is suitable for many applications. Its features include high-precision center frequency accuracy, long-term stability, and wide temperature range operation. Its low phase noise and holdover stability make it an ideal choice for applications that require precise reference frequencies. The TCO-7087X1A 20.0000M0 is an ideal choice for any application needing precise frequency control.
