CS11339-24M

Overview

The NDK CS11339-24M is a surface-mount crystal oscillator housed in a 2520 SMD package measuring 2.5 x 2.0 mm. It operates at a nominal frequency of 24 MHz with a base fundamental output type, eliminating the need for external harmonic processing circuits. The device maintains a frequency tolerance and stability of ±10 ppm across both room temperature (25°C) and the full operating range of -20°C to +70°C. Key electrical specifications include a maximum equivalent series resistance (ESR) of 60 Ω and a standard load capacitance (CL) of 8 pF. The unit supports a drive power level ranging from 10 mW to 200 mW, ensuring compatibility with most microcontroller oscillator pins without additional circuitry.

Feature Summary

• Compact 2520 surface-mount design suitable for space-constrained applications
• Base fundamental output eliminates requirement for external harmonic filtering
• Low equivalent series resistance ensures robust startup performance
• Standardized load capacitance simplifies peripheral circuit design

Applications

• General-purpose clock generation for microcontrollers
• Peripheral clock sources for consumer electronic devices
• Timing reference for standard UART and USB communication interfaces

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format and lead time constraints. Confirm that the component's operating temperature range aligns with the final product's environmental requirements. Ensure that the load capacitance specification is compatible with the target system's PCB trace parasitics to maintain frequency accuracy within specified tolerances.

Selection Notes

Select this component when a small footprint and moderate precision are required for general timing applications. Consider the ±10 ppm stability sufficient for standard digital interfaces but insufficient for high-precision RF synchronization. Evaluate the 60 Ω ESR limit against the oscillator circuit's startup requirements to ensure reliable operation across the specified temperature range.

Part Context

This model belongs to NDK's line of miniature surface-mount crystal oscillators designed for cost-effective timing solutions. The 2520 package offers a balance between size reduction and thermal/mechanical robustness compared to smaller footprints. It serves as a direct replacement for legacy through-hole or larger SMD crystals in modern compact electronics where space optimization is critical.
