18QHTF21-7.500-PD

Overview

The 18QHTF21-7.500-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.500 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, suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 7.500 MHz clock frequency. The LVCMOS output is appropriate for general-purpose digital logic interfacing. Consider the integrated power-down feature if system-level power efficiency is a priority. Verify that the small form factor fits within the available board space constraints.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down pin or function. This model specifically targets applications requiring precise timing at 7.500 MHz with low power consumption capabilities.

Replacement Considerations

Direct replacements must match the 7.500 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Other parts in the 18QHTF21 series with different frequencies may be compatible if the electrical parameters align. Cross-reference with other manufacturers offering similar SMD XO specifications.
