18QHTF21-17.320-OE

Oscillators Overview

The 18QHTF21-17.320-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 17.32 MHz and utilizes LVCMOS output logic levels. The device supports an active-low enable/disable function via the OE pin, allowing for power management control. It is housed in a compact 4-SMD surface-mount package with no lead construction, suitable for space-constrained electronic designs.

Oscillators Feature Summary

• Supports LVCMOS output interface for digital logic compatibility
• Features active-low enable/disable control via OE pin
• Utilizes lead-free 4-SMD surface-mount packaging

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Industrial automation systems requiring precise frequency references
• Embedded systems utilizing LVCMOS logic interfaces

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable/disable functionality, as this distinguishes it from standard variants without control pins. Ensure the package type matches the 4-SMD footprint requirements of the target PCB layout. Confirm that the 1.8V supply voltage aligns with the system's power domain before integration.

Oscillators Selection Notes

Select this component when a low-voltage LVCMOS output is required alongside power-saving capabilities through pin-controlled enablement. The 17.32 MHz frequency is specific; ensure it matches the exact timing requirements of the application circuit. Consider the small form factor if board space is limited, but verify thermal and mechanical constraints associated with the SMD package.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind., Co., Ltd. The series offers various frequencies and voltage options, all sharing a common compact SMD footprint. The '-OE' suffix indicates the inclusion of an output enable feature, providing additional system control flexibility compared to basic oscillator models within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical frequency and voltage but different suffixes, provided the OE pin functionality is not critical. Cross-referencing with other manufacturers requires matching LVCMOS output, 1.8V operation, and 4-SMD package dimensions.
