18QHTF21-72.000-PD

Overview

The 18QHTF21-72.000-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 72.0 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Generates a precise 72.0 MHz clock signal using standard XO technology
• Integrates LVCMOS output logic for direct digital interface compatibility
• Supports low-power operation through an active standby or power-down pin

Applications

• Digital signal processing systems requiring stable timing references
• Communication equipment utilizing LVCMOS-compatible interfaces
• Portable electronic devices necessitating low-voltage power consumption

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's noise sensitivity specifications to ensure reliable frequency generation without jitter-induced errors.

Selection Notes

Select this component when a 72.0 MHz frequency is required within a 2.0x1.6mm footprint constraint. Ensure the application circuit can provide a clean 1.8V supply and that the host device supports LVCMOS input thresholds. Consider the power-down feature if energy efficiency during idle states is a critical design parameter.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronic. The series typically offers various frequencies and voltage options within a standardized small outline package, providing designers with flexible timing solutions for space-constrained embedded applications.

Replacement Considerations

Direct substitutes include other 72.0 MHz LVCMOS oscillators in 4-SMD packages with identical 1.8V supply requirements. Verify pinout compatibility and thermal characteristics when cross-referencing with alternative manufacturers' offerings.
