18QHTF21-65.016-PD

Overview

The 18QHTF21-65.016-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 65.016 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic interface
• Standby power down capability
• Standard XO configuration

Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Procurement Notes

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

Selection Notes

Select this component when a precise 65.016 MHz clock source is needed with low voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature for power-sensitive designs requiring active control over oscillator operation. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates a specific pinout or packaging variant within the manufacturer's lineup. These components are designed for reliable timing in compact electronic devices.

Replacement Considerations

Direct substitutes may include other 65.016 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, NDK, or SiTime. Ensure equivalent electrical parameters such as supply voltage, current consumption, and phase noise specifications match. Verify mechanical dimensions and pin assignments for board-level compatibility.
