18QHTF21-4.6869-PD

Oscillators Overview

The 18QHTF21-4.6869-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 4.6869 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a power-down (standby) feature for energy management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode via power-down control
• Provides LVCMOS digital output signals
• Utilizes a small form-factor surface-mount package

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Embedded systems utilizing LVCMOS interfaces
• Compact timing circuits in space-constrained designs

Oscillators 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 PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a precise 4.6869 MHz clock signal is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage as a primary constraint for power budgeting. The integrated power-down capability makes it suitable for battery-operated applications where standby current reduction is critical for extending operational life.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based timing solutions. The series typically offers various frequencies within a standardized 2.0x1.6mm package. This specific model provides a lower frequency option compared to higher-speed variants in the same family, catering to slower clock domain requirements.

Oscillators Replacement Considerations

Direct substitutes must match the 4.6869 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if availability is an issue.
