18QHTF21-13.1313-OE

Overview

The 18QHTF21-13.1313-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.1313 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption during inactive periods. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Integrates LVCMOS output interface for digital signal compatibility
• Includes hardware enable and disable pin for power management
• Utilizes a leadless SMD package for space-constrained designs

Applications

• Embedded system clock generation
• Digital signal processing timing references
• Microcontroller peripheral synchronization

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure availability of the exact enable/disable variant. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails before procurement. Check for any recent updates to the mechanical dimensions or thermal specifications in the latest datasheet revision to ensure compatibility with existing board layouts.

Selection Notes

Select this component when a precise 13.1313 MHz reference is required for LVCMOS-compatible circuits. The integrated enable feature makes it suitable for battery-powered devices requiring active power states. Ensure the design supports the 1.8V operating voltage and accommodates the 4-SMD footprint constraints.

Part Context

This model belongs to the QHTF series of high-frequency oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within small form factors. This specific part represents a niche frequency option optimized for specialized communication or data transfer protocols requiring non-standard clock rates.

Replacement Considerations

Direct substitutes must match the 13.1313 MHz frequency, 1.8V supply, LVCMOS output, and enable functionality. Verify pinout compatibility for the 4-SMD package. Cross-reference with other Mercury Electronics models in the same series for potential drop-in replacements if available.
