18QHTF21-13.484-OE

Overview

The 18QHTF21-13.484-OE is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.484 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Provides stable timing signals via LVCMOS output interface
• Features low profile surface mount packaging for space-constrained designs
• Includes hardware enable/disable functionality for power management

Applications

• Precision timing applications in electronic devices
• Embedded systems requiring standard clock sources
• Consumer electronics utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific suffix (OE) to confirm the presence of the enable/disable pin, as this alters functional behavior compared to standard variants. Ensure the operating temperature range meets system requirements. Confirm RoHS compliance status through official documentation before integration into regulated products.

Selection Notes

Select this component when a 13.484 MHz clock signal is required with LVCMOS compatibility. The 1.8V supply voltage suits low-power digital circuits. The small 2.0x1.6 mm footprint allows placement in dense PCB layouts. Verify that the enable pin logic level aligns with the controlling microcontroller or FPGA outputs.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The OE suffix specifically denotes the inclusion of an output enable feature, distinguishing it from basic XO models without control pins.

Replacement Considerations

Direct substitutes include other 13.484 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation and enable pins. Verify pinout compatibility and electrical specifications before swapping. Generic replacements may lack the specific enable functionality unless explicitly documented.
