18QHTF21-13.09707-PD

Overview

The 18QHTF21-13.09707-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.09707 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The component is designed for applications requiring precise timing signals in low-voltage digital systems.

Feature Summary

• LVCMOS output interface for standard digital logic compatibility
• Integrated standby mode to reduce power consumption during idle periods
• Compact surface-mount package suitable for space-constrained designs

Applications

• General-purpose clock generation for microprocessors
• Timing reference for communication interfaces
• Digital signal processing circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout guidelines. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Selection Notes

Select this component when a precise 13.09707 MHz clock signal is required in a low-power environment. The LVCMOS output is suitable for standard CMOS logic families. Consider the 1.8V operating voltage if your system utilizes lower voltage domains compared to traditional 3.3V or 5V systems. The small form factor makes it ideal for portable or densely packed electronic devices where board space is limited.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized 2.0x1.6 mm package. These components are designed to replace through-hole crystals or larger oscillator packages in modern consumer electronics and industrial control systems requiring stable frequency sources.

Replacement Considerations

Direct substitutes must match the 13.09707 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Cross-reference with other manufacturers offering similar SMD oscillators only if they explicitly meet these exact parameters.
