18QHTF21-86.000-PD

Overview

The 18QHTF21-86.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 86 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Provides LVCMOS output signal compatibility

Applications

• General clock generation in embedded systems
• Timing reference for digital circuits
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 2.0x1.6 mm footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 86 MHz timing source is required within space-constrained designs. The choice is driven by the need for low-profile packaging and integrated power management features. Consider the LVCMOS interface compatibility with downstream logic gates to ensure signal integrity without additional buffering components.

Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors suitable for modern electronics. The PD suffix indicates the inclusion of a power-down pin, distinguishing it from continuous-operation variants within the same family.

Replacement Considerations

Direct substitutes include other 86 MHz LVCMOS oscillators in 2.0x1.6 mm packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as jitter and phase noise to ensure functional equivalence in the application.
