Key Specifications

The SX5M4.9152B10F20TNN boasts several critical specifications that define its performance and suitability for diverse applications:

• Output: CMOS – This specifies the output logic level, indicating compatibility with standard CMOS (Complementary Metal-Oxide-Semiconductor) digital circuits. CMOS outputs are widely used due to their low power consumption and high noise immunity, making this oscillator versatile for integration into most digital systems.
• Series: 5C – The ‘5C’ series designation from SCTF often indicates a specific family of oscillators known for particular performance characteristics or package types. This series likely signifies a balance of performance, size, and cost-effectiveness.
• Frequency: 4.9152MHz – This is the precise operating frequency at which the oscillator generates its output signal. 4.9152MHz is a common frequency often used in serial communication (UART) applications, as it can be easily divided to achieve standard baud rates without significant error.
• Size (mm): 5.0×3.2×1.20 – This indicates the physical dimensions of the component in millimeters, highlighting its compact nature. A small footprint is crucial for modern electronic designs where miniaturization and high component density are paramount.
• Input Current: 10-40mA – This range specifies the typical current drawn by the oscillator during operation. Understanding the input current is vital for power supply design and overall power budget calculations in the host system.
• Mounting Type: Surface Mount – This refers to the method of attaching the component to a printed circuit board (PCB). Surface Mount Devices (SMD) are standard in contemporary electronics manufacturing, enabling automated assembly and higher component density compared to through-hole components.
• Component Type: Crystal Oscillator – This explicitly identifies the device as a crystal oscillator, distinguishing it from simple crystals or resonators by its integrated oscillating circuit.
• Package / Case: 4-SMD – This describes the physical enclosure and pin configuration. A 4-SMD package is a common, compact form factor for crystal oscillators, facilitating efficient PCB layout and automated pick-and-place assembly.
• Supply Voltage: 1.8V, 2.5V, 3.3V – This indicates the range of compatible operating voltages. The ability to operate at multiple common logic voltages (1.8V, 2.5V, 3.3V) makes this oscillator highly adaptable to various system architectures and power requirements, from low-power portable devices to standard digital circuits.
• Frequency Range: 1 – 160MHz – While the specific output is 4.9152MHz, this attribute suggests the broader frequency capabilities of the oscillator family or design, indicating the manufacturer’s expertise across a wide spectrum of timing solutions.
• Frequency Stability: ±50ppm – This parameter measures how much the output frequency can deviate from its nominal value over a specified range of conditions, such as temperature or aging. A stability of ±50ppm (parts per million) is a good indicator of reliable performance for many general-purpose applications.
• Frequency Tolerance: ±20ppm – This indicates the maximum permissible deviation of the actual output frequency from the nominal frequency at a specified reference temperature (usually 25°C). A tighter tolerance (lower ppm value) signifies higher initial accuracy.
• Operating Temperature: -40℃ to +85℃, -40℃ to +105℃, -40℃ to +125℃ – This broad range of operating temperatures highlights the oscillator’s robustness and suitability for industrial, automotive, and other demanding environments where extreme thermal conditions are common. The availability of multiple temperature grades allows designers to select the most appropriate and cost-effective option for their specific application.
