18QHTF21-64.99584-PD

Overview

The 18QHTF21-64.99584-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 64.99584 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby (power down) control feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power reduction
• Provides LVCMOS signal output compatibility

Applications

• General digital timing circuits
• Embedded system clock generation
• Communication interface synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. 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 to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Choose this component when a precise 64.99584 MHz reference is required for low-power applications. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6mm form factor for space-constrained designs where thermal management and power consumption are critical factors for long-term reliability.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, a supplier specializing in quartz crystals and oscillators. The series typically offers surface-mount solutions designed for modern electronics manufacturing. Mercury has a history of producing frequency control components, providing options for various industrial and consumer electronic timing needs.

Replacement Considerations

Direct substitutes must match the 64.99584 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package. Alternative parts from other manufacturers should be evaluated for identical electrical characteristics and thermal performance to ensure seamless integration without redesign.
