18QHTF21-43.050-OE

Oscillators Overview

The 18QHTF21-43.050-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 43.05 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Enable/Disable functionality for power control
• Compact surface-mount package design

Oscillators Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific suffix OE to confirm the Enable/Disable feature, as other suffixes like PD indicate Standby mode. Ensure the 1.8V supply voltage matches the target circuit requirements. Confirm the 43.05 MHz frequency tolerance and load capacitance specifications against the official datasheet before integration.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS clock source is required with active power control capabilities. The small 2.0x1.6 mm footprint makes it suitable for space-constrained designs. Compare with the PD variant if standby power-down functionality is preferred over simple enable/disable control.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and output types. The -OE suffix specifically denotes the Enable/Disable control option, distinguishing it from standard or power-down variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-43.050-PD, which offers similar electrical characteristics but uses a Standby (Power Down) control mechanism instead of Enable/Disable. Verify that the control logic polarity and current consumption differences are acceptable for the application.
