18QHTF21-86.016-PD

Overview

The 18QHTF21-86.016-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 86.016 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down (standby) function to reduce consumption when inactive. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode for power management
• Provides standard LVCMOS signal output

Applications

• Embedded system clock generation
• Digital signal processing interfaces
• Communication module timing sources

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 is stable and within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues.

Selection Notes

Select this component when a precise 86.016 MHz reference is required in space-constrained designs. The choice is driven by the need for low-power standby capabilities and compatibility with 1.8V logic families. Evaluate thermal performance and stability requirements to ensure it meets the environmental conditions of the final application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages, sharing the same small form factor. The PD suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same physical package family.

Replacement Considerations

Direct substitutes must match the 86.016 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise to ensure functional equivalence without redesigning the host circuit.
