18QHTF21-83.333-PD

Overview

The 18QHTF21-83.333-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 83.333 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 with dimensions of 2.0x1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability
• Compact surface-mount form factor

Applications

• General clock signal generation
• Embedded system timing
• Digital circuit synchronization

Procurement Notes

Verify the specific datasheet from Mercury Electronic Ind. Co. Ltd to confirm exact electrical parameters and mechanical tolerances. Ensure compatibility with the target 1.8V supply rail and LVCMOS interface requirements before integration. Confirm that the 4-SMD no-lead package aligns with the PCB footprint design.

Selection Notes

Select this component when a precise 83.333 MHz reference is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital systems. Verify thermal performance and load capacitance requirements against the host circuit specifications to ensure stable oscillation.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants.

Replacement Considerations

Direct substitutes must match the 83.333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics with alternative manufacturers if sourcing changes are necessary.
