18QHTF21-58.250-OE

Overview

The 18QHTF21-58.250-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 58.25 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications.

Feature Summary

• LVCMOS output interface
• Enable/Disable control capability
• Compact 4-SMD No Lead package

Applications

• General clock generation
• Embedded systems timing
• Consumer electronics

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply voltage aligns with the system power rails. Confirm that the enable/disable pin configuration matches the host controller's GPIO capabilities to ensure proper power state management during operation.

Selection Notes

Select this component when a low-voltage 1.8V supply is available and space constraints require a small SMD footprint. The enable/disable feature is critical for battery-powered applications requiring power savings. Verify that the LVCMOS output swing is compatible with the input thresholds of the downstream digital logic or microcontroller.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same package form factor. The series provides standardized timing solutions for portable devices. The 'OE' suffix typically denotes the presence of an enable pin, distinguishing it from non-enabled variants in the same family.

Replacement Considerations

Direct replacements must match the 58.25 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Check datasheets for equivalent parts from other manufacturers ensuring identical pinout and electrical characteristics to maintain board compatibility.
