18QHTF21-12.600-PD

Overview

The 18QHTF21-12.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.6 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, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

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

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Procurement Notes

Verify the specific suffix PD against official Mercury Electronics documentation to confirm package and tape/reel specifications. Ensure the 1.8V supply requirement aligns with target system design. Confirm lead-free status and RoHS compliance through current manufacturer declarations before procurement.

Selection Notes

Select this component when a 12.6 MHz LVCMOS clock source is required in a minimal footprint. The 1.8V operating voltage dictates compatibility with low-voltage logic families. The 4-SMD package necessitates appropriate PCB land pattern design for reliable soldering.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent form factors. The PD suffix typically denotes specific packaging or handling characteristics within the manufacturer's catalog.

Replacement Considerations

Direct substitutes include other 12.6 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson, SiTime, or TXC. Verify pinout compatibility and electrical parameters before substitution.
