18QHTF21-4.7625-OE

Oscillators Overview

The 18QHTF21-4.7625-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 4.7625 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an active-low enable/disable control pin (OE). It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This component is engineered for timing applications requiring precise clock signals in space-constrained electronic designs.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Includes an active-low enable/disable function for power management
• Utilizes a small form factor 4-SMD no-lead surface mount package

Oscillators Applications

• General-purpose digital circuit timing
• Embedded system clock generation
• Consumer electronics signal synchronization

Oscillators Procurement Notes

Verify the specific suffix 'OE' confirms the presence of the enable pin functionality distinct from non-OE variants. Ensure the supply voltage requirement aligns with the 1.8V specification before integration. Confirm that the 4-SMD no-lead footprint matches the target PCB layout constraints to ensure proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside an enable control feature. The 4.7625 MHz frequency is suitable for specific baud rate or sampling requirements. Consider the 2.0x1.6mm package size for high-density board layouts. Compare against other Mercury series parts if different frequencies or voltage levels are needed for the application.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 18 prefix indicates the 1.8V supply variant, while the 21 denotes the package type. The OE suffix specifically identifies the version with an output enable pin, differentiating it from standard continuous-output models within the same physical footprint.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinouts and enable functionality but different frequencies, such as 18QHTF21-4.000-OE or 18QHTF21-8.000-OE, provided the frequency change is acceptable for the design.
