NSC5153A-32.768K

Overview

The NSC5153A-32.768K is a standard CMOS crystal oscillator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a frequency of 32.768 kHz and supports a supply voltage of 1.8V. The device features a standby function for power-down capability. It is designed for surface-mount application with a specified operating temperature range of -40°C to 85°C.

Feature Summary

• CMOS output signal format
• Integrated standby mode for power management
• Standard frequency stability for timing applications

Applications

• Embedded systems
• Industrial automation
• Real-time clock circuits

Procurement Notes

Verify the specific package dimensions and pin configuration against the official NDK datasheet prior to PCB layout finalization. Confirm that the 1.8V supply rail meets the required tolerance levels for stable oscillator operation. Ensure the selected footprint matches the surface-mount requirements specified in the manufacturer's mechanical drawings to guarantee proper soldering and thermal performance during assembly.

Selection Notes

Select this component when a low-power, standard-frequency CMOS oscillator is required for timekeeping or synchronization tasks. Consider the 1.8V supply constraint and the -40°C to 85°C temperature range to ensure compatibility with the target system's power architecture and environmental conditions. Evaluate the standby feature if power conservation is a critical design requirement for the end application.

Part Context

This model belongs to the NSC series of oscillators from NDK, which are engineered for compact electronic designs. The series typically offers various frequency options and supply voltages to suit different embedded needs. The NSC5153A variant specifically targets applications requiring reliable 32.768 kHz timing signals with low power consumption and standard CMOS interface compatibility.

Replacement Considerations

Consult official NDK documentation for direct cross-references. Verify electrical parameters such as supply voltage, frequency stability, and output type before substituting with other manufacturers' components to ensure functional equivalence.
