18QHTF21-13.514-PD

Overview

The 18QHTF21-13.514-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.514 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, specifically identified as a 4-VDFN with dimensions of 3.2x2.5 mm. This component is designed for surface mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power reduction
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel configuration matches your assembly requirements. Confirm that the 1.8V supply voltage aligns with your system's power rails before integration. Ensure the 4-VDFN footprint dimensions are compatible with your PCB layout constraints. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this oscillator when a stable 13.514 MHz reference is required for LVCMOS-compatible digital loads. Consider the 1.8V operating voltage constraint against your available power supplies. The small 4-SMD form factor makes it suitable for space-constrained designs. Evaluate the need for standby functionality if power efficiency is a critical design parameter for the target application.

Part Context

This component belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series typically offers various frequencies within the standard XO category. Mercury Electronics is a specialized manufacturer of frequency control products, including quartz crystals and oscillators, with a focus on providing reliable timing solutions for electronic systems.

Replacement Considerations

Direct replacements must match the 13.514 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications such as load current and duty cycle. Consult official substitution lists from Mercury Electronics or authorized distributors for validated equivalent parts.
