NX2016AB-38.4MHZ SWW

Overview

The NX2016AB-38.4MHZ SWW is a surface-mount crystal oscillator manufactured by NDK, designed for compact electronic applications. It operates at a nominal frequency of 38.4 MHz with a frequency tolerance of ±20 ppm. The device utilizes a fundamental resonance mode and features an equivalent series resistance (ESR) of 60 Ohms maximum. It is specified with a load capacitance (CL) of 7 pF. The component is housed in a small 4-SMD, no-lead package with dimensions of 2.0 mm by 1.6 mm, making it suitable for space-constrained designs.

Feature Summary

• Compact 2016 SMD footprint optimized for high-density PCB layouts
• Fundamental oscillation mode eliminating the need for overtone suppression circuits
• Low equivalent series resistance supporting reliable startup in low-power circuits

Applications

• Wireless LAN modules requiring precise clock references
• Bluetooth and BLE communication devices
• Miniature IoT sensor nodes

Procurement Notes

Verify the specific suffix against official NDK documentation to confirm exact electrical tolerances and temperature ranges. Ensure the ordering code matches the required load capacitance and frequency stability specifications for your design. Cross-reference the datasheet for any recent updates to the part number structure or manufacturing location details before finalizing procurement.

Selection Notes

Select this component when board real estate is limited and a 38.4 MHz reference is required. Confirm that the host microcontroller's oscillator circuit can drive the 60 Ohm ESR limit without excessive power consumption. Validate that the ±20 ppm tolerance meets the system's timing requirements across the intended operating temperature range.

Part Context

This part belongs to the NX2016 series, a line of ultra-small crystal units developed for wearable technology and portable electronics. The series emphasizes miniaturization while maintaining stable frequency performance. It serves as a direct replacement for larger 3225 packages where size reduction is critical for product form factor.

Replacement Considerations

Direct substitutes must match the 2016 package, 38.4 MHz frequency, 7pF load capacitance, and ≤60Ω ESR. Verify that alternative vendors offer identical fundamental mode operation and thermal characteristics to ensure pin-to-pin compatibility.
