Key Specifications

The Output type is CMOS, which refers to Complementary Metal-Oxide-Semiconductor logic. CMOS outputs are widely used due to their low power consumption and high noise immunity, making them ideal for driving digital circuits effectively. The Series, designated as 3C, often indicates a specific product line or family from the manufacturer, potentially signifying certain performance characteristics or package styles. The core specification is its Frequency of 148.5MHz, which is the precise oscillation rate it generates, crucial for applications requiring high-speed clocking. Its compact Size (mm) of 3.2×2.5×0.95 highlights its miniature footprint, enabling integration into densely packed PCBs. The Input Current range of 10-40mA specifies the operational current draw, an important factor for power budget calculations in portable or low-power designs. As a Surface Mount component, it is designed for automated assembly processes, reducing manufacturing costs and increasing production efficiency. The Component Type is a Crystal Oscillator, a self-contained module that includes the crystal and the oscillating circuit. The Package / Case is a 4-SMD, indicating a four-pin surface-mount device, which is standard for many compact oscillators. It supports multiple Supply Voltage options: 1.8V, 2.5V, and 3.3V, offering flexibility for integration into various power supply architectures. The broader Frequency Range of 1 – 160MHz indicates that this particular series can produce frequencies within this spectrum, with 148.5MHz being a specific variant. Frequency Stability of ±50ppm (parts per million) measures how much the output frequency deviates over time, temperature, and voltage changes, with lower values indicating higher precision. Frequency Tolerance of ±20ppm specifies the maximum allowable deviation of the actual frequency from the nominal 148.5MHz at room temperature. Finally, the wide Operating Temperature range of -40℃ to +85℃, -40℃ to +105℃, and -40℃ to +125℃ signifies its robustness and suitability for harsh industrial and automotive environments, ensuring reliable operation across extreme thermal conditions.
