18QHTF21-62.222-PD

Overview

The 18QHTF21-62.222-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 62.222 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) control function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component supports surface mount technology for automated assembly processes.

Feature Summary

• Supports low voltage CMOS output interface
• Includes standby power down functionality
• Compact surface mount package design

Applications

• Digital signal processing circuits
• Communication equipment timing
• Microcontroller clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no lead package footprint matches the PCB layout constraints. Check for any specific RoHS compliance documentation if required by the manufacturing facility standards.

Selection Notes

Select this component when a precise 62.222 MHz clock signal is required for LVCMOS compatible digital systems. The choice is driven by the need for a low-profile surface mount solution with integrated power management capabilities. Consider the operating temperature range and stability requirements to ensure reliable performance under the intended environmental conditions.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co. Ltd. The series offers various frequency options within a standardized 2.0x1.6mm package format. The suffix PD indicates the inclusion of a power down pin or function, distinguishing it from standard continuous operation variants in the same family.

Replacement Considerations

Direct substitutes must match the 62.222 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics and pinout compatibility before replacement.
