18QHTF21-13.574-PD

Overview

The 18QHTF21-13.574-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 13.574 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a standby mode for power down capabilities. 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 interface
• 1.8V supply voltage operation
• Standby (Power Down) capability

Applications

• Precision frequency generation
• Low power consumption systems
• Timing clock circuits

Procurement Notes

Verify the specific manufacturer designation, as sources list both Mercury Electronics Ind. Co. Ltd and Mercury United Electronics, Inc. Confirm the exact package dimensions and electrical specifications against the official datasheet to ensure compatibility with your circuit design requirements before finalizing procurement.

Selection Notes

Select this component when a 13.574 MHz frequency is required with low voltage operation. Consider the 4-SMD no-lead package for space-constrained designs. Ensure the application supports LVCMOS logic levels and can utilize the standby feature if power management is a priority.

Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based supplier specializing in quartz crystals, oscillators, filters, TCXOs, and VCTCXOs. The company has a history dating back to 1973 and is recognized as a pioneer in the Taiwanese quartz crystal industry, providing frequency control products globally.

Replacement Considerations

Other models in the 18QHTF21 series, such as 18QHTF21-18.1059-PD or 18QHTF21-51.200-PD, share the same package and logical interface but operate at different frequencies. Substitution requires matching the specific frequency requirement of the target application.
