Noise characterization is 5.5pF Capacitance (20dB), typ. @3V, 7.5pF Cap. max. @3V, and the rise/fall time is 2.1/2.7 nsec.

Application Field

The SG-636PCW 33.0000MC3:ROHS oscillator can be used in a variety of fields given its high frequency stability. It is commonly used in radio constellations, communications, and aerospace applications. It also serves as an ideal device for prototyping and embedded system applications where higher temperature tolerance, lower power consumption, and low EMI is a requirement.

Functions and Working Principle

The oscillator functions in a closed-loop system that uses a frequency-temperature correction and an amplifier. The SG-636PCW 33.0000MC3:ROHS oscillator integrates an internal voltage-controlled oscillator (VCO) along with an amplifier, a frequency tuning resistor, and an external frequency correction resistor. Signal output from the amplifier is then fed back to the VCO where it is compared to a reference frequency input. The difference is used to adjust the frequency output from the VCO.

The resistor network is carefully calibrated to adjust the frequency response of the system over temperature. The network adjusts for parameter drift over the temperature operating range of the product, resulting in a stable output frequency. This temperature compensating network also ensures small variations in operating voltages do not result in frequency changes.

Conclusion

The SG-636PCW 33.0000MC3:ROHS oscillator is a highly stable frequency device for a host of applications in the fields of radio constellations, communications, and aerospace engineering. Its frequency stability is due to its internal voltage-controlled oscillator working in conjunction with an amplifier and a frequency tuning resistor, which can be used to adjust the frequency output depending on the application. This device adheres to RoHS requirements making it environment-friendly and thus an ideal choice for many applications.
