18QHTF21-100.006-PD

Overview

The 18QHTF21-100.006-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 100.006 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6mm. This component is designed for precise timing applications requiring low power consumption and small form factor integration.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power reduction
• Compact surface-mount package design

Applications

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

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with system requirements. Confirm the 4-SMD package footprint matches the PCB layout to avoid assembly issues. Check for any RoHS compliance documentation if required by project specifications.

Selection Notes

Select this oscillator when a 100.006 MHz reference is required with LVCMOS outputs. Consider the 1.8V supply constraint and the need for a standby function. The 2.0x1.6mm size suits space-constrained designs. Compare performance metrics such as phase noise and stability against alternative models if stricter timing precision is needed.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS format. The series provides consistent packaging and electrical characteristics across different frequency options, facilitating inventory management and design reuse across multiple product lines.

Replacement Considerations

Direct substitutes include other 100MHz LVCMOS oscillators in similar packages from Mercury Electronics, such as the 18QHTF21-100.000-PD, provided frequency accuracy permits. Verify pinout and voltage compatibility before substitution.
