18QHTF21-103.667-PD

Overview

The 18QHTF21-103.667-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 103.667 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down function for standby mode control. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports standard XO operation with LVCMOS output compatibility
• Includes standby capability via power-down pin functionality
• Designed for low-voltage applications requiring 1.8V supply

Applications

• General clock signal generation in electronic circuits
• Systems requiring precise timing references at 103.667 MHz
• Compact embedded devices utilizing SMD packaging

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. 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 to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a fixed frequency of 103.667 MHz is required with LVCMOS interface compatibility. Consider the 1.8V operating voltage constraint and the need for power-down functionality. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs where standard leaded packages cannot fit within the available board area.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 4-SMD no-lead package. The series supports LVCMOS outputs and includes power-down features across different frequency options, providing a consistent platform for designers needing reliable clock sources in compact footprints.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical 2.0x1.6mm footprints and 1.8V LVCMOS specifications, such as the 18QHTF21-15.700-PD or 18QHTF21-96.000-PD, provided the frequency difference is acceptable for the application.
