Key Specifications

The SX2M33.3333B10F20TNN boasts several key specifications that define its performance and suitability for various applications:

• Output: CMOS – This specifies the logic family of the output signal. CMOS (Complementary Metal-Oxide-Semiconductor) output is widely used due to its low power consumption, high noise immunity, and compatibility with a broad range of digital ICs, making it a versatile choice for many designs.
• Series: 2C – The series designation often indicates a specific product line or family from the manufacturer, potentially signifying certain performance characteristics, package types, or target applications within SCTF’s portfolio.
• Frequency: 33.3333MHz – This is the nominal operating frequency of the oscillator, meaning it generates a clock signal at precisely 33.3333 million cycles per second. This specific frequency is often chosen for its compatibility with standard bus speeds or as a derivative for other clock frequencies through frequency dividers or multipliers.
• Size (mm): 2.5×2.0×0.81 – This indicates the physical dimensions of the component in millimeters. The compact size of 2.5mm by 2.0mm with a height of 0.81mm makes it suitable for space-constrained applications, typical in modern miniaturized electronic devices.
• Input Current: 10-40mA – This range specifies the typical current drawn by the oscillator from its power supply. Understanding this is crucial for power budget calculations and ensuring the power supply can adequately support the component’s operation.
• Mounting Type: Surface Mount – Surface Mount Technology (SMT) allows for automated assembly, higher component density, and improved electrical performance compared to through-hole components, making it the dominant mounting type in contemporary electronics manufacturing.
• Component Type: Crystal Oscillator – This explicitly identifies the device as a crystal oscillator, distinguishing it from other timing components like resonators or standalone crystals, as it integrates the crystal and the oscillating circuit into one package.
• Package / Case: 4-SMD – The 4-SMD package refers to a Surface Mount Device with four terminals, a common configuration for crystal oscillators, facilitating easy integration onto printed circuit boards.
• Supply Voltage: 1.8V, 2.5V, 3.3V – This oscillator supports multiple standard supply voltages, offering flexibility for designers to integrate it into systems operating at different logic levels, from low-power 1.8V to standard 3.3V.
• Frequency Range: 1-160MHz – While this specific part operates at 33.3333MHz, the stated frequency range indicates the broader capabilities of the oscillator family or series, suggesting that other variants within this family can produce frequencies from 1MHz up to 160MHz.
• Frequency Stability: ±50ppm – Frequency stability measures how much the output frequency deviates from its nominal value over temperature, voltage, and aging. A ±50ppm (parts per million) stability is a good indicator for many general-purpose and communication applications, ensuring consistent timing.
• Frequency Tolerance: ±20ppm – Frequency tolerance refers to the maximum allowable deviation of the actual output frequency from the specified nominal frequency at a reference temperature (typically 25°C). A ±20ppm tolerance indicates a high degree of initial accuracy.
• Operating Temperature: -40℃ to +85℃, -40℃ to +105℃, -40℃ to +125℃ – This oscillator is designed for robust operation across a wide range of industrial and automotive temperatures, indicating its suitability for harsh environments where temperature fluctuations are common, ensuring reliable performance in diverse applications.
