18QHTF21-86.400-PD

Overview

The 18QHTF21-86.400-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 86.4 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes standby mode capability to reduce power consumption
• Utilizes a small form factor 4-SMD no lead package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 86.4 MHz
• Embedded devices utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no lead package dimensions fit the PCB footprint constraints. Cross-reference the part number suffix PD with manufacturer documentation to confirm availability and specifications.

Selection Notes

Select this component when an 86.4 MHz clock source with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for low-power digital designs. The standby feature allows for power optimization in battery-operated or energy-sensitive applications. Verify that the 4-SMD package size meets the spatial requirements of the assembly process.
