STDCIX1-38.4M

Overview

The STDCIX1-38.4M is a surface-mount crystal resonator manufactured by NDK, designed for high-frequency applications requiring precise timing. Operating at a fundamental frequency of 38.4 MHz, this component delivers a frequency stability of ±10 ppm and a tolerance of ±15 ppm. It features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 100 Ohms. The device is housed in a compact 4-SMD, No Lead package with dimensions of 1.2 mm x 1.0 mm and a maximum height of 0.4 mm. Certified to AEC-Q200 standards, it supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in automotive environments.

Feature Summary

• AEC-Q200 qualified for automotive-grade reliability
• Compact 1.2x1.0 mm footprint for space-constrained designs
• Wide temperature operation from -40°C to +125°C
• High frequency stability of ±10 ppm

Applications

• Automotive infotainment systems
• Advanced driver-assistance systems (ADAS)
• In-vehicle communication modules
• Telematics control units

Procurement Notes

Verify the specific ordering suffix against the official NDK datasheet to ensure correct packaging and tolerance specifications. Confirm that the required frequency stability and load capacitance align with the target circuit design. Check for RoHS3 compliance requirements if applicable to the end product. Ensure the selected variant meets the thermal management needs of the application within the specified operating temperature range.

Selection Notes

Select this component when a small form factor is critical alongside automotive qualification. The 38.4 MHz frequency is suitable for clocking processors or communication interfaces requiring moderate speed. Consider the ±10 ppm stability requirement against system jitter budgets. The low profile aids in automated assembly processes for dense PCB layouts.

Part Context

This part belongs to the NX3225SA or similar SMD crystal series from NDK, which focuses on miniaturization and automotive durability. NDK utilizes proprietary quartz cultivation technology to achieve high performance in harsh environments. This series complements larger packages like the NX5032SA by offering smaller footprints without compromising electrical characteristics.

Replacement Considerations

STDCRS2-27M is listed as an equivalent part number by distributors, though frequency differs. Verify pin compatibility and electrical parameters before substitution. No other direct substitutes are confirmed in public documentation.
