18QHTF21-21.100-OE

Oscillators Overview

The 18QHTF21-21.100-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 21.1 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Integrates enable and disable functionality for power management
• Provides stable clock signals using LVCMOS output logic
• Designed for low-voltage operation at 1.8V

Oscillators Applications

• Precision timekeeping systems
• Digital signal processing circuits
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific suffix (OE) to confirm the presence of the enable pin functionality, as this distinguishes it from variants without control features. Ensure the operating temperature range meets the environmental requirements of the target application. Confirm that the 1.8V supply voltage aligns with the system's power rails before integration.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator with active control capabilities is required. The 2.0x1.6 mm footprint suits space-constrained designs. Verify compatibility with LVCMOS interfaces in the receiving circuitry. Consider the 1.8V supply requirement against available power sources in the design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The OE suffix indicates the inclusion of an enable pin, allowing for dynamic control of the oscillator output state within electronic circuits.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in a 4-SMD 2.0x1.6mm package with enable functionality. Verify frequency accuracy and load capacitance specifications match the original design requirements before substitution.
