18QHTF21-13.226-PD

Overview

The 18QHTF21-13.226-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.226 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) control function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component supports a specific operating temperature range suitable for electronic applications requiring precise timing signals.

Feature Summary

• Supports Standby (Power Down) mode for power management
• Utilizes LVCMOS output logic interface
• Compact 4-SMD No Lead surface mount package

Applications

• General purpose timing clock generation
• Embedded system microcontroller clocks
• Digital signal processing circuits

Procurement Notes

Verify the exact frequency suffix matches the required 13.226 MHz specification during procurement. Confirm the PD suffix indicates the Power Down feature availability. Ensure the 1.8V supply voltage aligns with the target circuit design requirements before ordering.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a power-down capability. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Verify that LVCMOS output compatibility exists with the receiving digital logic inputs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which includes various frequencies such as 8.000 MHz and 51.200 MHz. All variants share similar physical dimensions and electrical characteristics, differing primarily in their nominal output frequency and specific application tuning.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts like 18QHTF21-13.300-PD if frequency tolerance allows. Cross-brand replacements must match the 1.8V supply, LVCMOS output, and 4-SMD no lead package constraints.
