18QHTF21-48.806-OE

Oscillators Overview

The 18QHTF21-48.806-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 48.806 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm and a maximum seated height of 0.80mm.

Oscillators Feature Summary

• Compact surface-mount design suitable for space-constrained applications
• Integrated enable/disable functionality for power management
• LVCMOS output interface for digital circuit compatibility

Oscillators Applications

• Timing and synchronization in electronic devices
• Clock signal generation for digital systems

Oscillators Procurement Notes

Verify the specific operating voltage and load requirements against the target system design before procurement. Confirm that the 1.8V supply rail is stable and within tolerance to ensure accurate frequency performance. Ensure the PCB footprint matches the 2.0mm x 1.6mm SMD package dimensions and that reflow soldering profiles comply with the manufacturer's thermal specifications for no-lead components.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 48.806 MHz clock source. Consider the small form factor if board real estate is limited. Verify that the LVCMOS output swing is compatible with the input thresholds of the receiving logic circuits. Evaluate the need for the enable pin feature if dynamic power saving is a design priority.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which specializes in quartz crystal oscillators. The manufacturer has a history of producing frequency control products since 1973. This specific model represents a standard frequency option within their portfolio of surface-mount oscillators designed for general timing applications.

Oscillators Replacement Considerations

The 3QHTF22-48.806-PD is a related variant offering the same frequency but operates at 3.3V instead of 1.8V. Direct substitution requires verifying voltage compatibility and potential logic level differences between LVCMOS outputs.
