18QHTF21-1.0448-OE

Overview

The 18QHTF21-1.0448-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.0448 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The component supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50ppm.

Feature Summary

Supports active enable/disable functionality for power management
Compact surface-mount design suitable for space-constrained applications
LVCMOS output interface compatible with standard digital logic

Applications

Embedded systems requiring precise timing references
Consumer electronics with low-power requirements
Industrial control modules operating in varying temperatures

Procurement Notes

Verify the specific suffix 'OE' indicates the Enable/Disable pin configuration when sourcing replacements. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles or storage conditions.

Selection Notes

Select this component when a low-profile oscillator with enable control is required. The 1.0448 MHz frequency suits specific baud rate or clock division needs. Consider the ±50ppm stability for general-purpose timing rather than high-precision navigation. The 1.8V operation makes it suitable for modern low-voltage digital circuits.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'OE' suffix typically denotes the presence of an enable pin, distinguishing it from constant-output variants like 'PD'. This family targets applications needing flexible power management through software control.
