18QHTF21-27.092-PD

Oscillators Overview

The 18QHTF21-27.092-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 27.092 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a power-down capability for standby mode control. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes power-down functionality to enable standby mode operation
• Utilizes a small form factor 4-SMD no-lead package design

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded devices requiring low-voltage clock inputs

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 27.092 MHz timing source is required within space-constrained designs. The choice is driven by the need for low-voltage operation at 1.8V and the integration of power-down capabilities for energy management. The small physical profile makes it suitable for applications where board real estate is limited compared to larger through-hole or standard SMD packages.

Oscillators Part Context

This model belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series is characterized by its use of quartz crystal technology to provide stable frequency outputs. The 'PD' suffix indicates the inclusion of power-down control functionality, distinguishing it from continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 27.092 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in official datasheets.
