CS15187-12.288M

Overview

The NDK CS15187-12.288M is a surface-mount crystal oscillator operating at a fundamental frequency of 12.288 MHz. It features a load capacitance of 8 pF and a frequency tolerance of ±15 ppm. The component has an equivalent series resistance (ESR) of 100 Ohms and utilizes a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm x 0.60mm. It operates within a temperature range of -10°C to +75°C and complies with RoHS3 standards.

Feature Summary

• Fundamental mode operation for stable timing signals
• Compact 4-SMD surface-mount footprint for automated assembly
• Compliance with RoHS3 environmental regulations

Applications

• Digital clock circuits requiring precise timekeeping
• Microcontroller system clocks
• Communication interface timing references

Procurement Notes

Verify the specific datasheet version STD-CSR-1 against project requirements. Confirm that the 100 Ohm ESR and 8 pF load capacitance match the host circuit design. Ensure the -10°C to +75°C operating range is sufficient for the intended environment. Check for RoHS3 compliance documentation if required by regulatory standards.

Selection Notes

Select this component when a 12.288 MHz fundamental frequency is necessary for baud rate generation or clock division. The NX3225SA series offers a balance of size and performance. Consider the ±15 ppm stability limit for application accuracy. Evaluate the 100 Ohm ESR against the oscillator circuit's drive level constraints to prevent over-driving the crystal.

Part Context

This part belongs to the NX3225SA series of surface-mount crystals from NDK. The series provides various frequencies in a standardized 3.2x2.5mm package. The CS15187-12.288M specifically targets applications needing the 12.288 MHz frequency, which is derived from common base clock frequencies like 12.288 MHz or 24.576 MHz for digital audio and communication protocols.
