• Application Field

SG-8002JF 16.0000M-PCML0 PURE SN oscillators are used in a wide range of applications, such as in radio frequency (RF) and microwave technology, communications, wireless communications, avionics, medical devices, along with computer and consumer electronic applications. The oscillator circuit integrates both the oscillator and the frequency control for high level timing applications, and in order to provide stability and precision over frequency, temperature and aging, the oscillator must be continuously adjustable. As such, variable frequency oscillators have become increasingly important, especially in high performance systems.

The SG-8002JF 16.0000M-PCML0 (Pure SN) oscillator is a cutting-edge example of precision timing in the current market. This high frequency, voltage controlled oscillator (VCO) supports a wide range of frequencies from 16.0000MHz to 16.0001MHz, with a frequency stability of +/-0.001ppm (parts per million) over -40°C to +85°C and an aging rate of +/-0.02ppm/year. In addition to the precise frequency control, this oscillator offers a low phase noise, as low as -140dBc/Hz at 10kHz offset, a wide tuning voltage range from 0.4V to 3.3V and a low reference spurs level of -75dBc.

The SG-8002JF 16.0000MHz-PCML0 PURE SN oscillator is ideal for high accuracy applications where tight accuracy and stability are crucial, such as medical instrumentation, base station, mobile communication, wireless communication, GPS, navigation applications as well as medium and long distance point-to-point applications.

• Working Principle

SG-8002JF 16.0000M-PCML0 PURE SN oscillators are designed with an advanced voltage-controlled oscillator (VCO). The VCO consists of a PLL (phase-locked loop) containing a voltage-controlled oscillator (VCO) followed by a divider and a phase detector to afford the control loop. The VCO is driven by a DC electric, which is amplified to the elementary frequency of the oscillator. This divider feeds the current frequency to the phase detector. The phase detector compares the current frequency and the given frequency and a control voltage is generated. This control voltage is then fed back to the VCO and adjusts accordingly.

In order to increase the stability and accuracy of this oscillator, its circuit includes an adjustable capacitor divider, a band-pass filter and a temperature-compensated inductor. The capacitor divider is used to adjust the frequency and the band-pass filter is used to keep out false frequencies from interfering with the oscillator’s operation. Lastly, the inductor is used to keep the frequency stable against temperature fluctuations.

The advantage of the SG-8002JF 16.0000M-PCML0 PURE SN oscillator lies in its outstanding stability and precision over frequency, temperature, and aging. It also has an adjustable frequency range with a minimum step of 0.0001MHz, making it ideal for precision timing applications.
