18QHTF21-20.460-OE

Oscillators Overview

The 18QHTF21-20.460-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 20.46 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required frequency tolerance and load capacitance specifications. Confirm that the 1.8V supply voltage aligns with the target system design before procurement. Check for any recent updates to the RoHS compliance status or lead-free material declarations directly from official Mercury Electronic documentation.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator with enable functionality is required. Ensure the 20.46 MHz frequency matches the system clock requirements. Verify that the LVCMOS output swing is compatible with the receiving logic inputs. Consider the 4-SMD package dimensions for PCB layout constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronic. The series offers various frequencies with consistent LVCMOS outputs and enable features. The 'OE' suffix typically denotes a specific packaging or compliance variant within the manufacturer's lineup, distinct from other series like spread-spectrum models.

Oscillators Replacement Considerations

Direct substitutes must match the 20.46 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as jitter and stability before substitution.
