18QHTF21-40.730-OE

Oscillators Overview

The 18QHTF21-40.730-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 40.73 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features an Enable/Disable pin for active power control
• Utilizes a surface-mount 4-SMD no-lead package design

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices utilizing standard LVCMOS interfaces

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the Enable/Disable function, as this distinguishes it from standard variants without control pins. Ensure the operating voltage matches the 1.8V requirement of the target circuit design. Confirm the package footprint aligns with the 2.0x1.6 mm SMD dimensions during PCB layout validation.

Oscillators Selection Notes

Select this component when a precise 40.73 MHz timing source is required within space-constrained designs. The choice is appropriate for applications necessitating low-voltage 1.8V operation and standard CMOS output levels. Consider the Enable/Disable capability if dynamic power management is a system requirement compared to always-on oscillator alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators produced by Mercury Electronics. The series typically offers various frequencies and supply voltages. The specific model denotes a 40.73 MHz variant with LVCMOS outputs and enable functionality, distinct from other series members that may differ in package size or voltage specifications.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-40.730-PD, which shares the same frequency and package but may differ in the enable feature configuration. Verify functional equivalence regarding the output logic type and supply voltage before swapping components in existing designs.
