18QHTF22-45.600-PD

Oscillators Overview

The 18QHTF22-45.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 45.6 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a compact surface-mount package measuring 2.5mm in length, 2.0mm in width, and a height of 0.9mm. It supports a power-down function for standby mode and maintains a frequency stability of ±50ppm across the operating temperature range.

Oscillators Feature Summary

• LVCMOS output logic compatibility
• Integrated power-down control for energy efficiency
• Compact 2.5x2.0mm surface-mount footprint

Oscillators Applications

• General-purpose digital clock signal generation
• Embedded system timing references
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific order code suffix to ensure the correct tolerance and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the LVCMOS output swing is compatible with the receiving logic inputs.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V powered oscillator is required for space-constrained designs. The 45.6 MHz frequency suits applications needing precise timing without higher-frequency noise concerns. Consider the ±50ppm stability adequate for standard digital interfaces. Evaluate the power-down feature if battery life or thermal management is a priority in the system architecture.

Oscillators Part Context

This part belongs to the 18QHTF22 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The '-PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from always-on variants. It serves as a direct replacement for other 2.5x2.0mm 1.8V LVCMOS oscillators in existing layouts.

Oscillators Replacement Considerations

Direct substitutes must match the 2.5x2.0mm package, 1.8V supply, and LVCMOS output. Verify frequency accuracy and stability specifications against the original design margins. Ensure the pinout configuration is identical to avoid PCB rework.
