18QHTF21-13.507-PD

Overview

The 18QHTF21-13.507-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 13.507 MHz and utilizes LVCMOS output logic. The device is designed for surface mount applications, housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. It functions within an operating temperature range of -40°C to 85°C and supports a supply voltage of 1.8V. Key functional features include a standby mode for power down capabilities, ensuring efficient energy management in portable or battery-operated systems.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby function for power down control
• Compact 4-SMD no-lead surface mount package

Applications

• Portable electronic devices requiring low power consumption
• Digital signal processing circuits
• Communication equipment clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge sensitivity during assembly.

Selection Notes

Select this component when a precise 13.507 MHz clock signal is required in a minimal space-constrained environment. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V operation if power efficiency is a primary design constraint compared to higher voltage alternatives.

Part Context

This part belongs to the 18QHTF21 series of surface mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same physical form factor.

Replacement Considerations

Direct replacements must match the 13.507 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as current consumption and stability before substituting with components from other manufacturers.
