18QHTF21-75.695-PD

Overview

The 18QHTF21-75.695-PD is a 75.695 MHz XO (Standard) LVCMOS oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features a Standby (Power Down) function. The component is housed in a 4-SMD, No Lead package.

Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for digital interface compatibility.
• Includes a standby or power-down mode to reduce power consumption when not in use.

Applications

• General clock signal generation in electronic circuits
• Digital systems requiring standard frequency references
• Portable devices utilizing low voltage operation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and reliability data.

Selection Notes

Select this model when a precise 75.695 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power management is critical for the application environment.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various standard frequencies with consistent 1.8V operation and compact SMD packaging. Mercury Electronics is a recognized manufacturer of frequency control products.

Replacement Considerations

Direct substitutes must match the 75.695 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
