18QHTF21-13.530-PD

Overview

The 18QHTF21-13.530-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.53 MHz and utilizes LVCMOS output logic. The device is designed for surface mount applications in a compact 4-SMD, No Lead package with dimensions of 3.2x2.5 mm. It supports a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption during inactive periods.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features a low-profile 4-SMD no lead surface mount package
• Includes standby capability for power management

Applications

• General purpose timing clock generation
• Embedded system microcontroller clocks
• Consumer electronics signal processing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct pinout and electrical characteristics are selected. Confirm that the 1.8V supply requirement aligns with the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a precise 13.53 MHz reference is required for LVCMOS compatible circuits. Ensure the PCB layout accommodates the 3.2x2.5 mm footprint and that the power supply rail can provide stable 1.8V operation with adequate decoupling.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, a supplier specializing in quartz crystals and oscillators. The series offers various frequencies within a standardized small outline package format, allowing designers to maintain consistent board layouts across different timing requirements.

Replacement Considerations

Direct substitutes include other 13.53 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson, NDK, or SiTime, provided the pin configuration and voltage levels are identical.
