18QHTF21-72.330-OE

Overview

The 18QHTF21-72.330-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 72.33 MHz and utilizes an LVCMOS output logic level. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals in electronic circuits.

Feature Summary

• Standard XO configuration with LVCMOS output
• Integrated enable/disable functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment timing
• Embedded controller clock sources

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm exact electrical tolerances and pinout compatibility. Ensure the 1.8V supply requirement aligns with target circuit design before procurement. Cross-reference the 72.33 MHz frequency specification with system requirements to avoid timing mismatches in sensitive digital interfaces.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard 72.33 MHz reference frequency. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small 4-SMD footprint for space-constrained PCB layouts where traditional through-hole oscillators cannot fit.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, focusing on low-voltage crystal oscillators. The series typically offers various frequency options within a standardized small outline package. It serves as a timing reference solution for modern consumer electronics and industrial control systems requiring stable clock signals.

Replacement Considerations

Check for direct substitutes within the 18QHTF21 series offering identical 72.33 MHz frequencies and 1.8V operation. Verify pin-to-pin compatibility with other manufacturers' 4-SMD LVCMOS oscillators if sourcing alternatives. Ensure replacement parts maintain the same enable/disable logic polarity and operating temperature range.
