STDCRG2-14.7456M

Overview

The STDCRG2-14.7456M is a surface-mount crystal oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a nominal frequency of 14.7456 MHz with a frequency tolerance of ±20 ppm and stability of ±30 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. Designed for base mode operation, it supports a temperature range of -40°C to +85°C. The device is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 0.90mm maximum height. It complies with RoHS specifications and holds an MSL rating of 1.

Feature Summary

• Compact 4-SMD surface-mount package suitable for space-constrained designs
• Base mode operation ensuring stable frequency generation
• Compliance with RoHS environmental standards

Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and digital logic circuits
• Communication interface synchronization requiring standard baud rates

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration, as variations exist between tape-and-reel, cut tape, and Digi-Reel formats. Confirm that the required frequency tolerance and stability meet the target application's timing requirements before finalizing procurement. Check for any recent Product Change Notifications (PCNs) that may affect material composition or manufacturing location. Ensure compatibility with the intended load capacitance circuit design.

Selection Notes

Select this component when a 14.7456 MHz frequency is required for standard communication protocols or system clocks. Consider the 80 Ohm ESR value to ensure proper oscillation startup within the host circuit design. The -40°C to +85°C operating range suits most commercial and industrial applications. Verify that the 8 pF load capacitance matches the oscillator circuit's external capacitor values. Compare against alternative packages if board space constraints differ from the 3.2x2.5mm footprint.

Part Context

This part belongs to the NX3225GA series of surface-mount crystals from NDK. The series is designed for general electronic applications requiring reliable frequency control. The STDCRG2-14.7456M shares physical dimensions and mounting characteristics with other frequencies in the same series, allowing for potential design flexibility across different clock speeds within the same product family.
