18QHTF21-13.42422-PD

Overview

The 18QHTF21-13.42422-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a fixed frequency of 13.42422 MHz and utilizes LVCMOS output logic. 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, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode to reduce power consumption
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing circuits
• Communication equipment timing references
• Embedded system clock generation

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to ensure it matches the required pin configuration and packaging specifications. Confirm that the 1.8V supply voltage aligns with the target circuit design before procurement. Check for any recent revisions to the 18QHTF21 series documentation to ensure compliance with latest manufacturing standards.

Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 1.8V logic systems. The LVCMOS output is suitable for direct interfacing with microcontrollers and FPGAs. Ensure the operating temperature range specified in the official datasheet meets the environmental requirements of the final application.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration provided by the distributor or manufacturer for automated assembly processes.

Replacement Considerations

Direct substitutes must match the 13.42422 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify electrical parameters such as load capacitance and phase noise against the original specification to ensure functional equivalence.
