353NB5C122R is a general level wireless telecom oscillator from Abracon Corporation, an innovative leader in the design and manufacture of frequency control, signal conditioning, clock distribution, RF & microwave signal and power solutions. The oscillator features low power consumption, miniaturized size, and operates from its low capacitance series resonant quartz blank. Containing two servo-mechanism loops, (pulling and pushing) the oscillator is well-suited for use in low-cost low-power radio telecommunication applications.

Application Field

The 353NB5C122R from Abracon is designed for use as RF oscillator in telecommunications and other high frequency applications such as cellular base stations, cordless phone handsets, audio systems, modems, and other communications equipment. It can also be used in automotive, industrial, medical, and consumer applications requiring precision RF oscillation.

Working Principle

The working principle of the 353NB5C122R is based upon a pair of servo-mechanism loops. The pulling loop is used to maintain oscillation frequency accuracy, while the pushing loop is used to counteract the temperature variations that affect oscillation frequency. The two loops interact to generate a stable oscillation frequency by suppressing temperature variations caused by changes in the quartz blank. This ensures high-accuracy frequency control over a wide temperature range and under different load conditions.

The resonator used in the oscillator is a quartz blank which is configured in a series resonance configuration. This ensures low-noise operation and low power consumption. The series resonance circuit is characterized by high frequency and frequency stability accuracy, and it can filter out unwanted signals. The quartz resonator also provides excellent aging performance over time and also eliminates problems associated with mechanical and electrical vibration. The oscillator circuit is designed to ensure high accuracy frequency control over a wide range of temperatures and under different load conditions.

The 353NB5C122R oscillator offers high frequency accuracy and stability, plus low power consumption and miniaturized size, making it an ideal choice for high-frequency telecommunications and other applications that require precision oscillation. It is also designed to withstand extreme temperatures and also offers excellent aging performance over time.
