18QHTF21-1.832-OE

Overview

The 18QHTF21-1.832-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 1.832 MHz and utilizes LVCMOS output logic. The component is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Provides stable LVCMOS clock signals with enable/disable functionality
• Operates on a low 1.8V power supply for energy efficiency
• Utilizes a compact 4-SMD no-lead package for space-constrained designs

Applications

• General-purpose digital circuit timing
• Embedded system clock generation
• Low-power consumer electronics

Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm pinout and electrical characteristics. Ensure the 1.8V supply requirement aligns with target system voltages. Confirm package dimensions match PCB footprint requirements before finalizing procurement.

Selection Notes

Select this model when a low-frequency, low-voltage oscillator with enable control is required. Compare against other 18QHTF21 variants for frequency accuracy needs. Ensure compatibility with LVCMOS input thresholds of downstream components.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies within a small SMD form factor. It is distinct from TCXO or VCTCXO models which offer higher stability but different cost and performance profiles.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical package and voltage but different frequencies, such as 18QHTF21-1.000-OE. Verify that any replacement maintains the LVCMOS output type and 1.8V operating range.
