18QHTF21-27.100-PD

Oscillators Overview

The 18QHTF21-27.100-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 27.1 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby function for power down capabilities. 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 Standby mode functionality to reduce power consumption during inactive periods
• Utilizes a small form factor 4-SMD No Lead package design

Oscillators Applications

• General clock signal generation for electronic circuits
• Timing reference for low-voltage digital systems
• Embedded applications requiring compact oscillator solutions

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 27.1 MHz timing source is required for low-voltage applications. The LVCMOS output ensures direct interfacing with compatible logic families without additional buffering. The integrated standby feature makes it suitable for battery-powered or energy-efficient designs where power management is critical.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm footprint. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 27.1 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility for the standby control signal. Cross-reference with other manufacturers offering similar ultra-small form factor oscillators with identical electrical specifications.
