Oscillators are devices used to create alternating electrical signals, usually in the form of sine waves, square waves, or triangle waves. Among oscillators, DSC1103CI2-148.5000 is an economical integrated oscillator which combines a temperature-compensated MEMS oscillator, clock Buffer IC and passive components in one package. It provides superior phase noise and spectral purity and is an ideal choice for space-saving, low-cost, low-power, and high-performance applications.

DSC1103CI2-148.5000 Application Fields

DSC1103CI2-148.5000 is commonly used in consumer electronics, computer peripherals, wireless communication systems, optical modules, medical equipment, optical networks, industrial automation, automotive electronics and low frequency data transmission. Since the circuit is small (40 mm2) and low power (2.2 mW typical value), it can also be used in handheld and wearable devices that require high signal integrity, such as wearable heart-rate monitors and Bluetooth wireless headsets.

Working Principle

The DSC1103CI2-148.500 is an integrated, temperature-compensated MEMS oscillator. It comprises a resonator and a MEMS drive integrated circuit (MEMSIC) formed on a 4 μm CMOS process. The resonator is made of high quality LiNbO3 substrate with a high frequency-temperature coefficient of 8.8 ppm/°C for low-frequency stability. The MEMS IC processes the signal received from the resonator to provide a clean, low distortion sine wave output with low frequency stability and phase noise. The output sine wave amplitude is adjustable through an external resistor. The output sine wave frequency can be selected from a range of 138MHz to 194MHz.

The MEMSIC includes a frequency generating circuit, an oscillator, a frequency multiplication circuit, and a buffer amplifier. The frequency generating circuit combines the received signal from the resonator with an adjustable external resistor, and produces an intermediate frequency (IF) signal. The oscillator then processes the IF signal to produce the output signal. The frequency multiplier increases the frequency of the output signal as needed, while the buffer amplifier is used to maintain the desired output voltage of the sine wave.

The DSC1103CI2-148.5000 provides superior phase noise performance and spectral purity due to its temperature compensated semiconductor components and unique circuit design. This makes it ideal for a variety of low-cost, low-power, high-performance oscillator applications.
