18QHTF21-27.095-PD

Oscillators Overview

The 18QHTF21-27.095-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.095 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output interface for digital compatibility
• Features standby mode to reduce power consumption during idle periods
• Utilizes surface-mount packaging for automated assembly

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring compact oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors.

Oscillators Selection Notes

Select this component when a precise 27.095 MHz timing source is required within space-constrained designs. The choice is driven by the need for low-voltage operation and integrated power-down capabilities. Consider the trade-off between the small form factor and thermal dissipation needs in high-density layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies tailored for different clocking applications. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 27.095 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available in competitor datasheets.
