18QHTF21-37.088-PD

Oscillators Overview

The 18QHTF21-37.088-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 37.088 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 in electronic circuits requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation with integrated standby capability
• Provides stable LVCMOS output signals for digital interfaces
• Utilizes a leadless surface-mount package for automated assembly

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing references
• Microcontroller clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package dimensions fit within the designated PCB footprint constraints to avoid mechanical interference during assembly.

Oscillators Selection Notes

Select this component when a 37.088 MHz reference is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage as a primary constraint for power-sensitive designs. Evaluate the need for standby functionality if power conservation is critical. Compare the physical dimensions of the 4-SMD package against available board space to ensure compatibility with existing manufacturing processes.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies with consistent electrical characteristics and packaging. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from non-disableable variants within the same form factor family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinouts and electrical specs but different frequencies, such as 18QHTF21-37.300-PD, provided the frequency difference is acceptable for the application.
