18QHTF21-13.502-OE

Overview

The 18QHTF21-13.502-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.502 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This surface-mount oscillator is suitable for space-constrained electronic designs requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

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

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD footprint matches the PCB layout requirements. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliability.

Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for digital logic interfaces. The LVCMOS output is appropriate for standard CMOS-compatible circuits. Consider the enable pin if power cycling or clock gating is necessary. Verify that the 13.502 MHz frequency meets the system's timing specifications. Evaluate thermal performance within the specified operating temperature range.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic Ind. Co., Ltd. The series typically offers various frequencies and voltage options within a standardized 2.0x1.6mm package. The 'OE' suffix likely indicates a specific packaging or tape-and-reel configuration, though exact details require datasheet confirmation. It represents a standard timing solution for modern compact electronics.

Replacement Considerations

Direct substitutes must match the 13.502 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Cross-reference with other manufacturers offering similar low-profile oscillators. Ensure pinout compatibility and electrical characteristics are identical. Verify that any alternative part supports the same enable/disable functionality.
