Introduction

DSC1102BI1-100.0000T is an oscillator belonging to the family of resonator-based oscillators, which provide a stable range of frequencies over wide temperature variations for applications ranging from data communication devices to compliance testing instruments. This oscillator features a temperature range of -20°C to +70°C, an output frequency of 100 MHz -200 MHz with a tolerance of 0.25% and is available in TO-220F surface-mount package or SMD4080 electrical connector packages.

Application Field

The DSC1102BI1-100.0000T oscillator is used for a variety of applications, such as for clock and timer circuits, radio frequency (RF) applications, and in communications and measurement systems. On the RF side, the oscillator is used to generate local oscillator (LO) frequencies in radio receivers, as a frequency synthesizer in wireless devices, and as a clock oscillator for communication products.In addition, due to its low power consumption and improved temperature stability, it is also suitable for use in instrumentation, telecom, medical, consumer electronics and communication devices, such as radio receivers, fixed radio systems and Cordless Telephones (CTs). The oscillator also offers a wide range of applications for consumer grade personal computer motherboards, medical equipment and electromechanical systems.

Working Principle

The DSC1102BI1-100.0000T oscillator is based on the traditional electrical resonator technology, in which an electrical circuit consisting of a resonator, an amplifier and a feedback network is used to maintain the oscillation of the signal at the desired frequency. The resonator of the oscillator is a quartz crystal cut from quartz mined in the earth\'s crust and precisely cut to a specific frequency. The crystal is placed in an oscillator circuit that is configured to form an LC tank circuit or a quartz-resonant oscillator. The LC tank circuit consists of two inductors connected in parallel with a capacitor consisting of the crystal resonator in the middle. The capacitive reactance of the crystal creates an LC tank circuit, which oscillates at its natural frequency, determined by the values of the inductors and capacitor. A drive amplifier is used to drive the LC tank circuit. The oscillator output signal is feedback in the oscillator circuit. The signal is compared to an internally generated reference signal and the resulting phase difference is used to determine the output frequency. The feedback signal is then amplified and used to adjust the LC tank resonant frequency. As a result, the crystal oscillator frequency is not dependent on the external environment.

Conclusion

The DSC1102BI1-100.0000T oscillator performs reliably over wide temperature ranges and provides a stable frequency output over a wide range of frequencies. It offers excellent performance, stability and accuracy for applications ranging from basic communication systems to more complex measurement technologies. This makes it an ideal choice for use in a variety of application fields.
