SX3M40.000A10F20TNN 40MHz CMOS 4-SMD Crystal Oscillator

SX3M40.000A10F20TNN is a high-performance 40MHz CMOS crystal oscillator manufactured by SCTF, a reputable name in passive components. This surface-mount device (SMD) is designed to provide a precise and stable clock signal, which is fundamental for the synchronous operation of digital circuits. As a crucial timing component, it converts electrical energy into mechanical vibrations and back, generating a highly accurate frequency output. Its compact 4-SMD package makes it ideal for space-constrained applications, offering a reliable timing solution across a wide range of operating conditions.

Key Specifications

The Output type is CMOS, which signifies that the oscillator produces a rail-to-rail output signal, making it directly compatible with most digital logic families. This simplifies interfacing and reduces the need for additional level-shifting circuitry. The Series, 3C, often indicates a specific product line from SCTF, potentially denoting certain performance characteristics or package styles within their crystal oscillator offerings. The fundamental Frequency of 40MHz is the primary clock speed generated by this component, suitable for microcontrollers, FPGAs, and various communication protocols requiring a precise 40MHz timing reference. Its compact Size (mm) of 3.2×2.5×0.95 highlights its miniature footprint, enabling high-density PCB designs and integration into small form-factor devices. The Input Current range of 10-40mA specifies the typical current consumption, providing crucial information for power budget calculations in battery-powered or low-power applications. As a Surface Mount component, it is designed for automated assembly processes, leading to cost-effective manufacturing and improved reliability compared to through-hole components. The Component Type is explicitly a Crystal Oscillator, distinguishing it from raw crystals or resonators by indicating it includes the necessary oscillating circuitry. The Package / Case is a 4-SMD, referring to its four solderable pads for surface mounting, a standard configuration for compact timing devices. The versatile Supply Voltage options of 1.8V, 2.5V, and 3.3V allow for broad compatibility with various logic families and power supply rails, enhancing its applicability across different system designs. The wide Frequency Range of 1 – 160MHz, while the specific part is 40MHz, indicates the broader capability of the series, suggesting other frequencies might be available in similar packages. The Frequency Stability of ±50ppm (parts per million) quantifies how much the output frequency can drift over temperature, voltage, and aging, with ±50ppm being a common and acceptable stability for many industrial and commercial applications. The Frequency Tolerance of ±20ppm specifies the initial deviation of the output frequency from its nominal 40MHz value at standard conditions, indicating the precision of the manufacturing process. Finally, the broad Operating Temperature range, specified as -40℃ to +85℃, -40℃ to +105℃, and -40℃ to +125℃, signifies its robustness and suitability for harsh industrial, automotive, and high-temperature environments, ensuring reliable operation under extreme conditions.
