SX1M38.400M10F30TNN

Oscillators Overview

The SX1M38.400M10F30TNN is an active crystal oscillator manufactured by Shenzhen SCTF Electronics, designed for surface-mount applications in the SOT-23-3 package. It operates at a nominal frequency of 38.4 MHz with a CMOS output mode. The device supports a supply voltage range of 1.62V to 3.63V and draws a typical operating current of 10mA. Frequency stability is specified at ±30ppm over temperature, while initial accuracy is maintained within ±10ppm. The component features an enable/disable function where the Output Enable (OE) pin must be held high or left floating to activate the frequency output.

Oscillators Feature Summary

• CMOS output interface compatible with standard digital logic levels
• Integrated enable/disable control via OE pin for power management
• Compact SOT-23-3 surface-mount package design
• Stable frequency generation within specified tolerance ranges

Oscillators Applications

Oscillators Procurement Notes

Verify that the specific suffix TNN matches the required tape-and-reel packaging configuration if automated assembly is planned. Confirm that the OE pin handling circuitry aligns with the high-level or floating activation requirement to ensure proper oscillator startup. Cross-reference the ±10ppm initial accuracy and ±30ppm total stability against system timing budgets to prevent synchronization errors in high-speed data links.

Oscillators Selection Notes

Select this model when a 38.4 MHz CMOS clock source is required within a constrained SOT-23-3 footprint. Ensure the host system provides a stable voltage between 1.62V and 3.63V to maintain performance. Consider the 10mA current draw for battery life calculations. This part is suitable for designs prioritizing size reduction and low-power operation without sacrificing frequency precision in standard industrial or commercial environments.

Oscillators Part Context

This oscillator belongs to the SCTF active crystal series, characterized by small form factors and CMOS outputs. It serves as a critical timing element in modern electronic assemblies where space efficiency and reliable clock distribution are paramount. The SOT-23-3 package allows for dense PCB layouts, making it ideal for portable devices and compact industrial controllers requiring precise temporal coordination.

Oscillators Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, CMOS output type, SOT-23-3 package, and 1.62V–3.63V voltage range. Verify equivalent ±10ppm/±30ppm stability specifications. Ensure any alternative component maintains identical enable/disable logic behavior on the OE pin to guarantee functional compatibility in existing circuits.
