18QHTF21-80.400-OE

Overview

The 18QHTF21-80.400-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 80.400 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Supports active enable and disable control states
• Utilizes a leadless surface-mount package design

Applications

• General clock signal generation
• Digital system timing references
• Embedded controller synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational specifications to ensure consistent performance. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions precisely to avoid assembly issues.

Selection Notes

Select this component when a precise 80.400 MHz reference is required for low-voltage digital systems. The LVCMOS output is suitable for direct interfacing with standard logic families. Consider the small form factor for space-constrained designs requiring reliable clock sources without external buffering.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies within a compact SMD package. These components are designed for general-purpose timing applications where size and low power consumption are critical factors in the overall system architecture.

Replacement Considerations

Direct substitutes include other 80.400 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as supply voltage and current consumption before swapping.
