18QHTF21-18.2912-PD

Oscillators Overview

The 18QHTF21-18.2912-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 18.2912 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a dedicated standby or power-down mode to minimize energy consumption when inactive. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly in space-constrained electronic designs.

Oscillators Feature Summary

• Supports LVCMOS output interface for digital logic compatibility
• Includes standby functionality for power management
• Utilizes a leadless SMD package for surface mounting

Oscillators Applications

• General purpose clock signal generation
• Low-power embedded systems
• Digital circuit timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Ensure the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided by the manufacturer to ensure proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a precise 18.2912 MHz reference is required with minimal power consumption. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V operating voltage constraint and the availability of the standby feature for battery-operated or energy-efficient applications requiring periodic sleep modes.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies and supports low-voltage operation. The 'PD' suffix indicates the inclusion of a power-down or standby pin/functionality, distinguishing it from continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 18.2912 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify if the replacement part includes the same standby functionality. Cross-reference with other Mercury Electronics models in the 18QHTF21 series or equivalent industry-standard oscillators with identical electrical and mechanical specifications.
