18QHTF21-37.3248-OE

Oscillators Overview

The 18QHTF21-37.3248-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 37.3248 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct interface with digital circuits
• Includes hardware enable/disable pin for active power state control
• Utilizes a leadless surface-mount package for automated assembly

Oscillators Applications

• Clock generation for high-speed data communication interfaces
• Timing reference for embedded microprocessor systems
• Synchronization source for consumer electronic devices

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable/disable functionality, as this alters the operational behavior compared to standard variants. Ensure the 1.8V supply rail is stable and within tolerance before integration. Confirm that the PCB footprint matches the 4-SMD no-lead specification to prevent soldering defects during reflow processes.

Oscillators Selection Notes

Select this model when a 37.3248 MHz clock signal is required with low-voltage compatibility. The enable feature makes it suitable for battery-powered designs where power conservation is critical. Compare against other frequencies in the 18QHTF21 series if different timing standards are needed while maintaining the same physical form factor and voltage requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies including 1.088 MHz, 12.1 MHz, and 44.2 MHz. All variants share similar packaging and voltage characteristics, differing primarily in output frequency and specific functional suffixes like OE or PD.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical 37.3248 MHz frequency and OE suffix. Cross-referencing with other manufacturers requires verifying LVCMOS compatibility and 1.8V operation. Ensure the replacement maintains the 2.0x1.6 mm footprint to fit existing board layouts.
