18QHTF21-38.800-OE

Oscillators Overview

The 18QHTF21-38.800-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 38.8 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount integration into electronic circuits requiring precise clock signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power control
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General electronics devices requiring clock synchronization
• Embedded systems utilizing LVCMOS interfaces
• Portable equipment with low-voltage power constraints

Oscillators Procurement Notes

Verify the manufacturer designation carefully, as similar part numbers may be listed under Mercury United Electronics, Inc. or other entities. Confirm the specific suffix '-OE' matches the required enable/disable feature and voltage specifications. Ensure the 4-SMD no-lead package type aligns with your PCB footprint requirements before finalizing procurement orders to avoid component mismatch issues.

Oscillators Selection Notes

Select this component when a 38.8 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for low-power applications. The enable/disable pin allows for dynamic power management. Verify that the 4-SMD no-lead package dimensions fit the available board space and that the manufacturing source is consistent with system reliability standards.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which provides various frequency options within a standardized small form factor. The series typically includes models with different frequencies such as 8.300 MHz and 37.888 MHz, sharing similar package and electrical characteristics. This specific model targets applications needing a precise 38.8 MHz reference signal with low voltage operation.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-37.888-OE and 18QHTF21-8.300-OE if frequency differences are acceptable. Other variants in the 18QHTF21 series may serve as alternatives provided they match the LVCMOS output, 1.8V supply, and enable/disable functionality.
