18QHTF21-65.280-PD

Overview

The 18QHTF21-65.280-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 65.28 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down standby function to reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down standby capability
• Provides LVCMOS output signal

Applications

• General electronic circuits requiring precise timing
• Embedded systems utilizing LVCMOS interfaces
• Portable devices necessitating low power consumption

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 specific operating temperature range limitations defined in the official datasheet.

Selection Notes

Select this component when a small form factor is required alongside low voltage operation. The LVCMOS interface ensures compatibility with standard digital logic families. The power-down feature makes it suitable for battery-operated applications where energy efficiency is critical during idle periods.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal products. The series offers various frequencies within a standardized 2.0x1.6mm SMD package. The 'PD' suffix indicates the inclusion of a power-down control pin for standby management.

Replacement Considerations

Direct substitutes must match the 65.28 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before swapping.
