18QHTF21-91.955-OE

Overview

The 18QHTF21-91.955-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 91.955 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality. It exhibits a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 85°C. The component utilizes a 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control capability
• Designed for surface mount assembly in compact form factors

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock inputs

Procurement Notes

Verify the specific frequency suffix matches the required 91.955 MHz specification. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD package footprint corresponds to the PCB layout constraints. Check that the ±50ppm stability meets the system timing tolerance requirements.

Selection Notes

Select this component when a low-profile surface mount oscillator is required for 1.8V logic systems. Consider the ±50ppm stability limit for applications requiring moderate precision. Evaluate the 2.0 x 1.6 mm package size against available board space. Verify the enable/disable pin configuration fits the power management strategy.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The OE suffix indicates specific ordering or packaging variations defined by the manufacturer. These components are designed for high-volume consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 91.955 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Frequency stability of ±50ppm or better is required. Operating temperature range of -40°C to 85°C must be maintained. Pinout compatibility for enable/disable functionality should be verified.
