18QHTF21-27.1631-PD

Oscillators Overview

The 18QHTF21-27.1631-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.1631 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby or power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output interface

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication equipment utilizing standard clock signals
• Embedded systems needing precise timing references

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 2.0x1.6mm SMD 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 small form factor and low voltage operation are critical. The LVCMOS output is suitable for direct interfacing with most digital logic families. Consider the power-down feature if battery life is a primary concern. Compare against other frequencies in the 18QHTF21 series to ensure the exact 27.1631 MHz rate meets your system's timing needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a consistent 2.0x1.6mm package. These components are designed for applications where space is limited and power efficiency is important. The 'PD' suffix indicates the inclusion of power-down capabilities.

Oscillators Replacement Considerations

Direct replacements must match the 27.1631 MHz frequency, 1.8V supply, and 2.0x1.6mm package. Verify output logic compatibility. Other Mercury parts in the same series may offer different frequencies but share similar physical characteristics.
