18QHTF21-75.385-OE

Overview

The 18QHTF21-75.385-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.385 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Integrates enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Features a leadless SMD package for surface mount assembly

Applications

• Clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Power-sensitive portable electronic devices

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage requirements. Ensure the operating temperature range and load capacitance specifications match the target circuit design before procurement.

Selection Notes

Select this component when a low-voltage 1.8V clock source is required with active power control capabilities. Consider the small 2.0x1.6mm footprint for space-constrained designs. Confirm that LVCMOS logic levels are compatible with the receiving input pins of the target microcontroller or FPGA.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package format designed for high-volume consumer and industrial electronics manufacturing.

Replacement Considerations

Direct substitutes must match the 75.385 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Generic replacements may lack the specific enable/disable functionality unless explicitly documented.
