18QHTF21-86.640-PD

Overview

The 18QHTF21-86.640-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 86.64 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby function for power down capabilities. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode for power management
• Utilizes 4-SMD no lead surface mount packaging

Applications

• Digital clock signal generation
• Data communication interfaces
• Microcontroller system timing

Procurement Notes

Verify the specific ordering suffix to ensure correct frequency and package configuration. Confirm that the 1.8V supply requirement aligns with the target circuit design. Check for RoHS compliance status if environmental regulations apply. Ensure the 4-SMD footprint matches the PCB layout constraints. Validate the operating temperature range against the intended application environment.

Selection Notes

Select this component when a stable 86.64 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint during power budgeting. The small form factor makes it suitable for space-constrained designs. Evaluate the need for standby functionality for power-sensitive applications. Compare against other frequencies in the 18QHTF21 series if different timing is needed.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 4-SMD package. Mercury Electronics is a Taiwan-based manufacturer with a history in quartz crystal production since 1973. The series supports standard LVCMOS outputs and low voltage operation.

Replacement Considerations

Other parts in the 18QHTF21 series may serve as substitutes if frequency differences are acceptable. Verify pinout and electrical characteristics before substitution. Direct replacements require identical frequency and package dimensions.
