18QHTF21-75.430-OE

Overview

The 18QHTF21-75.430-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 75.43 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 2.0mm x 1.6mm.

Feature Summary

• Integrates LVCMOS output logic for digital signal compatibility
• Features integrated enable and disable control functionality
• Utilizes a leadless surface-mount package design

Applications

• General clock signal generation in electronic circuits
• Data communication interface timing sources
• Embedded system processor clocking

Procurement Notes

Verify the specific manufacturer designation, as sources list both Mercury Electronics Ind. Co. Ltd and Mercury United Electronics, Inc. Confirm current availability status, as some distributors indicate this product may no longer be available. Ensure the 1.8V supply requirement matches the target circuit design before procurement.

Selection Notes

Select this component when a precise 75.43 MHz clock source is required with low-voltage operation. The 1.8V supply constraint necessitates compatible power rails. The small 2.0x1.6mm footprint suits space-constrained designs. Verify that LVCMOS logic levels align with the receiving input thresholds of the connected components.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic Industrial Co., Ltd. The series typically offers various frequencies and supply voltages. The 'OE' suffix likely denotes a specific ordering or packaging variant. Mercury is a recognized manufacturer of quartz crystal and frequency control products based in Taiwan.

Replacement Considerations

Direct substitutes within the same series include models such as 18QHTF21-86.8875-OE and 18QHTF21-30.0075-OE, which share similar package and logic characteristics but differ in operating frequency. Cross-reference pinouts and electrical specifications carefully when considering alternative frequencies.
