18QHTF21-91.750-OE

Overview

The 18QHTF21-91.750-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 91.75 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output interface
• Enable/Disable control pin
• Surface-mount SMD package

Applications

• Digital signal processing systems
• Communication equipment
• Embedded computing modules

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage and frequency specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to integration into production lines. Ensure that the enable/disable functionality aligns with system power sequencing requirements.

Selection Notes

Select this component when a 1.8V supply voltage and LVCMOS output are required for a 91.75 MHz clock source. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the enable/disable feature meets the power management strategy of the target application.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or tape-and-reel configuration details as defined by the manufacturer's catalog.

Replacement Considerations

Direct substitutes must match the 91.75 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD package dimensions. Cross-reference with other Mercury QHTF variants or equivalent industry components ensuring identical pinout and electrical characteristics.
