The SX7M4.9152B10F20TNN is part of the broader category of SMD MHz Crystal Oscillators, offering a compact and efficient solution for modern electronic designs requiring accurate timing.

Key Specifications

Output: CMOS – This specification indicates that the oscillator provides a Complementary Metal-Oxide-Semiconductor (CMOS) compatible output signal. CMOS logic is widely used in digital circuits due to its low power consumption and high noise immunity, making this oscillator suitable for direct interfacing with most microcontrollers, FPGAs, and other digital ICs without additional level shifting circuitry.

Series: 7C – The ‘7C’ series designation from SCTF often denotes a specific family of crystal oscillators known for particular performance characteristics, package types, or target applications. Understanding the series helps in identifying other compatible or related components from the same manufacturer and understanding the design lineage.

Frequency: 4.9152MHz – This is the fundamental operating frequency of the oscillator. A 4.9152MHz signal is a common frequency used in various digital communication protocols, microcontrollers, and data processing applications, providing a precise clock source for timing-critical operations.

Size (mm): 7.0×5.0×1.30 – This refers to the physical dimensions of the component in millimeters. The compact 7.0mm by 5.0mm footprint with a low profile of 1.30mm makes it ideal for space-constrained applications, allowing for higher component density on printed circuit boards (PCBs) and enabling miniaturization of end products.

Input Current: 10-40mA – This range specifies the typical current consumption of the oscillator. A relatively low input current is beneficial for battery-powered devices and power-sensitive applications, contributing to longer battery life and reduced overall power budget.

Mounting Type: Surface Mount – Surface Mount Technology (SMT) allows the component to be mounted directly onto the surface of a PCB. This method is standard in modern electronics manufacturing, facilitating automated assembly processes, reducing manufacturing costs, and enabling smaller form factors compared to through-hole components.

Component Type: Crystal Oscillator – This clearly identifies the device’s function as a self-contained unit that generates an oscillating electrical signal using a quartz crystal, distinguishing it from passive crystals that require external circuitry to oscillate.

Package / Case: 4-SMD – The 4-SMD package indicates a Surface Mount Device with 4 pins or pads for electrical connection. This standard package type is robust and facilitates efficient automated pick-and-place assembly.

Supply Voltage: 1.8V, 2.5V, 3.3V – This oscillator is designed to operate across multiple common digital supply voltages, offering flexibility for integration into systems powered by 1.8V, 2.5V, or 3.3V rails. This multi-voltage compatibility simplifies power management in mixed-voltage designs.

Frequency Range: 1 – 160MHz – While the specific operating frequency is 4.9152MHz, this attribute indicates the broader frequency range that components within this series or family are capable of supporting. It highlights the manufacturer’s capability in producing oscillators for diverse frequency requirements.

Frequency Stability: ±50ppm – Frequency stability measures how much the output frequency can deviate from its nominal value over time, temperature, and voltage variations. A stability of ±50 parts per million (ppm) is excellent for many commercial and industrial applications, ensuring reliable timing performance.

Frequency Tolerance: ±20ppm – Frequency tolerance specifies the maximum allowable deviation of the actual output frequency from the nominal frequency at a specified reference temperature (usually 25°C). A ±20ppm tolerance ensures high initial accuracy, critical for applications requiring precise timing from the outset.

Operating Temperature: -40℃ to +85℃, -40℃ to +105℃, -40℃ to +125℃ – This wide range of operating temperatures signifies the oscillator’s robustness and suitability for harsh environmental conditions. The ability to function reliably from extreme cold to high heat makes it suitable for industrial, automotive, and outdoor applications where temperature fluctuations are common.
