18QHTF21-86.623-PD

Overview

The 18QHTF21-86.623-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 86.623 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device supports standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby capability to reduce power consumption during idle states
• Utilizes a leadless SMD package for automated surface-mount assembly

Applications

• Digital signal processing systems requiring precise clock synchronization
• Communication equipment utilizing standard frequency references
• Embedded control units needing low-voltage timing sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors. Cross-reference the datasheet for thermal management guidelines related to the leadless form factor.

Selection Notes

Select this component when a standard LVCMOS clock source is required at 86.623 MHz with a 1.8V supply. Consider the leadless package size constraints and thermal dissipation characteristics. Evaluate the need for standby functionality to optimize system power efficiency. Compare performance metrics against alternative oscillators if tighter jitter or phase noise specifications are necessary for the application.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same physical footprint. The series provides standardized LVCMOS outputs suitable for general-purpose digital timing. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from non-stby variants within the same family.

Replacement Considerations

Direct replacements must match the 86.623 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical parameters such as duty cycle and rise/fall times. Consult manufacturer substitution lists for equivalent parts with identical mechanical and electrical specifications.
