18QHTF21-13.41875-PD

Overview

The 18QHTF21-13.41875-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.41875 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby and power-down functionality for power management
• Utilizes a base crystal resonator for frequency generation

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package dimensions fit within your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a stable 13.41875 MHz reference is needed with low power consumption capabilities. The LVCMOS output is suitable for standard digital logic families. Consider the operating temperature range and absolute pull range if environmental stability is critical. The compact form factor makes it appropriate for space-constrained designs.

Part Context

This part belongs to the Mercury Electronics XO series, which provides precision frequency control products. Mercury Electronic has been manufacturing quartz crystals and oscillators since 1973, establishing itself as a pioneer in the Taiwan crystal industry. The product line includes various types such as TCXO, VCTCXO, and OCXO, catering to diverse frequency control needs.

Replacement Considerations

Direct substitutes may include other models from the same 18QHTF21 series with different frequencies, such as 18QHTF21-15.700-PD or 18QHTF21-13.396875-PD, provided the frequency difference is acceptable. Cross-brand replacements require matching voltage, output type, and package dimensions.
