18QHTF21-27.230-PD

Oscillators Overview

The 18QHTF21-27.230-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.23 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports RoHS compliance standards.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

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 27.23 MHz reference is needed with minimal power usage. The small 2.0x1.6mm form factor suits space-constrained designs. Consider the LVCMOS compatibility with your digital inputs. Evaluate the need for standby functionality to extend battery life in portable applications.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized small outline package. The series typically includes options for different supply voltages and output types. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 27.23 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as jitter and stability before swapping manufacturers.
