18QHTF21-64.000-PD

Overview

The 18QHTF21-64.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 64 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby (power down) feature for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode to reduce power consumption during idle periods
• Designed for surface-mount assembly using a leadless SMD package

Applications

• Digital signal processing systems requiring precise clock timing
• Communication equipment utilizing standard CMOS interfaces
• Portable electronic devices necessitating low-power operation modes

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 PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability.

Selection Notes

Select this component when a 64 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage and standby functionality if power efficiency is critical. Evaluate the 4-SMD No Lead form factor for space-constrained designs. Compare against other frequencies in the 18QHTF21 series if different timing specifications are needed.

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 indicates the inclusion of a power-down capability. These components are designed for general-purpose timing applications in consumer and industrial electronics.

Replacement Considerations

Direct substitutes within the same series include models such as 18QHTF21-51.200-PD or 18QHTF21-76.000-PD, which share identical packaging and electrical characteristics but differ in frequency. Verify that the alternative frequency meets the system requirements before substitution.
