18QHTF21-38.864-OE

Oscillators Overview

The 18QHTF21-38.864-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 38.864 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features enable/disable control functionality. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface
• Enable/Disable control capability
• Compact surface-mount form factor

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the enable/disable function versus power-down variants. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 4-SMD no-lead package compatibility with the PCB footprint. Cross-reference the exact frequency specification against application requirements.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for space-constrained designs. The enable/disable feature allows for power management during idle states. Consider the small 2.0x1.6mm footprint for high-density board layouts. Verify temperature range specifications if operating in extreme environments.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'OE' suffix typically denotes the enable/disable pin configuration. This model specifically targets applications requiring precise timing at 38.864 MHz.

Oscillators Replacement Considerations

Direct substitutes may include other 38.864 MHz LVCMOS oscillators in 4-SMD packages. Verify voltage compatibility and pinout definitions before substitution. Check mechanical height constraints as alternatives may differ slightly. Ensure frequency stability specifications meet the original design intent.
