18QHTF21-93.312-OE

Overview

The 18QHTF21-93.312-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 93.312 MHz and utilizes LVCMOS output logic. The component requires a 1.8V supply voltage and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The device is designed for applications requiring precise timing signals within specified operating temperature ranges.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes hardware enable and disable functionality for active power control
• Utilizes a leadless surface-mount package for automated assembly processes

Applications

• High-speed data communication interfaces requiring precise clock synchronization
• Embedded systems utilizing microcontrollers or processors needing stable timing references
• Consumer electronics devices requiring low-voltage operation and compact form factors

Procurement Notes

Verify the specific suffix (OE) against the manufacturer's current datasheet to confirm pinout configuration and electrical characteristics. Ensure the required 1.8V supply voltage aligns with the target system design. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check for any environmental compliance certifications required for the specific application region.

Selection Notes

Select this component when a 93.312 MHz frequency is strictly required for system timing. Consider the 1.8V supply constraint and ensure the PCB layout supports the small 4-SMD footprint. Evaluate if the enable/disable feature provides necessary power savings compared to always-on oscillators. Verify that the operating temperature range meets the environmental conditions of the final product deployment.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages within a standardized small outline package. These components are commonly used in portable electronics and industrial equipment where space constraints and power efficiency are critical design parameters.

Replacement Considerations

Direct substitutes must match the 93.312 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pin-to-pin compatibility before replacement. Alternative parts from other manufacturers may require schematic adjustments if supply voltages or output logic families differ.
