18QHTF21-75.340-OE

Overview

The 18QHTF21-75.340-OE is a 75.34 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The device features an enable/disable control function via the OE pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes enable/disable functionality through dedicated control pin
• Designed for low voltage operation at 1.8V

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific suffix 'OE' corresponds to the enable/disable feature and LVCMOS output type as documented. Confirm the operating temperature range and frequency stability specifications against the official datasheet before integration. Ensure the 1.8V supply voltage aligns with the target system design requirements.

Selection Notes

Select this component when a precise 75.34 MHz clock source is required for systems operating at 1.8V. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. The enable/disable feature allows for power management optimization in battery-operated applications requiring periodic clock activity.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized 4-pin SMD package format. The 'OE' suffix typically denotes the inclusion of an output enable control mechanism distinct from standard continuous-output variants.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical 75.34 MHz frequency, 1.8V supply, and OE control features. Verify pin compatibility and electrical specifications match exactly before substitution.
