18QHTF21-106.813186-PD

Overview

The 18QHTF21-106.813186-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 106.813186 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down capability for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby and power-down functionality to reduce power consumption
• Utilizes a leadless SMD package for automated surface-mount assembly

Applications

• High-speed data communication systems
• Network infrastructure equipment
• Consumer electronics requiring precise clocking

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent soldering defects during assembly.

Selection Notes

Select this component when a stable 106.813186 MHz reference is required for LVCMOS-compatible digital circuits. The choice is driven by the need for low-power operation via the standby feature and the space constraints addressed by the small form factor. Consider thermal performance and operating temperature range relative to the final application environment.

Part Context

This part belongs to the 18QHTF21 series of quartz oscillators from Mercury Electronics. The series is characterized by its use of standard crystal technology and support for various frequencies. The 'PD' suffix indicates the inclusion of power-down control, distinguishing it from continuous-operation variants within the same family.

Replacement Considerations

Direct replacements must match the 106.813186 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if available in public documentation for candidate substitutes.
