18QHTF21-105.000-PD

Overview

The 18QHTF21-105.000-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 105 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component features a Standby mode for power down capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes Standby functionality to enable power down operations
• Utilizes a small form factor 4-SMD No Lead package

Applications

• General clock signal generation in electronic circuits
• Power management systems requiring standby modes
• Compact embedded device timing applications

Procurement Notes

Verify the specific part number against official Mercury Electronics documentation to ensure compatibility with system requirements. Confirm that the 1.8V supply voltage and LVCMOS logic levels align with the target design specifications before procurement.

Selection Notes

Select this component when a 105 MHz clock source is required within a constrained footprint. Ensure the design supports the 1.8V operating voltage and accommodates the 4-SMD No Lead package dimensions. Verify thermal and electrical characteristics against the official datasheet.

Part Context

This model belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and operates at 1.8V. The 'PD' suffix indicates the inclusion of a power-down or standby feature, distinguishing it from standard continuous-operation variants.

Replacement Considerations

Consult official Mercury Electronics substitution lists for verified equivalents. Cross-reference frequency, voltage, and package dimensions to ensure functional compatibility without modifying the host circuit layout.
