18QHTF21-62.860-PD

Overview

The 18QHTF21-62.860-PD is a 62.86 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features LVCMOS output levels. The device provides ±50ppm frequency stability and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby and power-down functionality
• Delivers standard LVCMOS signal output

Applications

• General clock generation for digital circuits
• Embedded systems requiring low power consumption
• Portable electronic devices

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 4-SMD no-lead package footprint matches the design layout. Ensure the 1.8V supply requirement aligns with the target system's power rails to guarantee proper oscillator performance and stability.

Selection Notes

Select this component when a small form factor is required alongside low voltage operation. The 1.8V specification suits modern low-power logic families. Consider the ±50ppm stability for applications where moderate precision is sufficient. The integrated power-down feature offers advantages in battery-operated designs requiring extended standby times.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on ultra-small surface-mount oscillators. The series typically covers various frequencies while maintaining a consistent 2.0x1.6 mm footprint. This specific model targets high-density PCB layouts where space constraints are critical.

Replacement Considerations

Direct substitutes must match the 62.86 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify compatibility with existing firmware or clock distribution networks. Cross-reference pinouts and electrical characteristics with alternative manufacturers offering similar miniature oscillator solutions.
