18QHTF21-107.6923-PD

Overview

The 18QHTF21-107.6923-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 107.6923 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

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

Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded control circuits

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. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a stable 107.6923 MHz clock source is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage as a primary constraint for power-sensitive designs. Evaluate the small 2.0x1.6mm package size against available board space. The standby feature offers an advantage for battery-powered or energy-efficient applications.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and clock oscillators. The series typically offers various frequencies within a standardized 4-SMD package format. Mercury Electronics has been a manufacturer of frequency control products since 1973, positioning itself as a provider for obsolete and hard-to-find frequency devices.

Replacement Considerations

Direct substitutes must match the 107.6923 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar XO specifications if availability is a concern.
