18QHTF21-14.18757-OE

Oscillators Overview

The 18QHTF21-14.18757-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 14.18757 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Standard crystal oscillator configuration with LVCMOS output interface
• Integrated enable and disable functionality for power control
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose digital circuit timing
• Embedded systems requiring stable clock references
• Consumer electronics with low voltage requirements

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required enable/disable logic and voltage levels. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Cross-reference the part number with official Mercury Electronics documentation to validate availability and manufacturing status before procurement.

Oscillators Selection Notes

Select this component when a precise 14.18757 MHz clock signal is required for LVCMOS-compatible circuits. The 1.8V supply requirement makes it suitable for low-power portable devices. Ensure the design accommodates the enable/disable pin functionality if dynamic power management is necessary. Verify thermal and mechanical constraints associated with the small form factor package.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a similar package profile. The '-OE' suffix likely denotes specific electrical or packaging variations defined by the manufacturer. This component represents a specialized timing solution within the broader quartz crystal and oscillator product line offered by the company.

Oscillators Replacement Considerations

Direct substitutes must match the 14.18757 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Check Mercury Electronics for updated revisions. Other manufacturers may offer equivalent frequencies but require verification of pinout and electrical characteristics.
