18QHTF21-62.000-PD

Overview

The 18QHTF21-62.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 62 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component features a power-down capability for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes power-down functionality to reduce power consumption during standby
• Designed as a standard XO (Crystal Oscillator) unit

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current documentation to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Check for any recent revisions to the datasheet regarding mechanical tolerances or thermal characteristics.

Selection Notes

Select this component when a low-profile 2.0x1.6 mm footprint is required for space-constrained designs. Ensure the system operates at 1.8V to match the specified supply voltage. Consider the LVCMOS output level compatibility with downstream logic gates. Verify that the 62 MHz frequency meets the precise timing requirements of the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various frequencies and voltage options within the same small SMD package family. Mercury Electronics has been manufacturing these components since 1973, establishing them as a supplier in the Taiwan crystal industry.

Replacement Considerations

Direct substitutes include other 62 MHz LVCMOS oscillators in 4-SMD No Lead packages with 1.8V operation. Cross-reference with similar Mercury models like 18QHTF21-51.200-PD if frequency adjustment is possible, though exact frequency matching is required for direct replacement.
