The CF5019 series are high-frequency, third overtone crystal oscillator module ICs. They integrate an oscillator circuit and an output buffer that function at high frequencies on a single chip. The oscillator circuit utilizes CMOS inverters and a built-in damping resistor RD, which decreases the crystal current compared to existing devices. The damping resistor RD is manufactured using NPC's unique high-precision thin-film resistor technology, which minimizes oscillator characteristic variations due to fluctuations in temperature and voltage. The CF5019 series can be employed to create stable, high-frequency, third overtone crystal oscillators by Nippon Precision Circuits Inc. (NPC).

The CF5019 series of ICs is specifically designed for applications requiring stable and precise frequency generation. The integration of the oscillator circuit and output buffer within a single chip simplifies the design process, reduces the size of the overall circuit, and enhances reliability. The CMOS inverter configuration is notable for its low power consumption and high noise immunity, making it suitable for high-frequency operations.

The built-in damping resistor RD plays a critical role in improving the performance of the oscillator. By reducing the crystal current, it helps to extend the life of the crystal and enhance the overall stability of the oscillator's output frequency.
