18QHTF21-62.860-OE

Overview

The 18QHTF21-62.860-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 62.86 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, supporting a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This surface-mount oscillator is suitable for space-constrained electronic designs requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the operating temperature range suitability for your intended environment.

Selection Notes

Choose this oscillator when a 62.86 MHz reference is needed in a minimal footprint. The LVCMOS output is ideal for direct connection to digital logic inputs. Consider the 1.8V operation for low-power portable devices. The enable pin allows for dynamic power saving during idle periods. Compare size requirements against larger packages if space permits alternative options.

Part Context

This component belongs to the Mercury Electronics XO series, which focuses on standard frequency oscillators. The 18QHTF21 prefix indicates a specific form factor and electrical characteristic set within their product line. Mercury Electronic Ind. Co., Ltd. is a manufacturer specializing in quartz-based frequency control products. This series targets applications requiring reliable timing sources in small electronic modules.

Replacement Considerations

Direct substitutes must match the 62.86 MHz frequency, LVCMOS output, and 1.8V supply voltage. Compatible replacements should offer identical 4-SMD no-lead packaging dimensions. Verify that any alternative part supports the same enable/disable control logic. Ensure the replacement maintains similar phase noise and stability specifications for critical timing applications.
