18QHTF21-13.484-PD

Overview

The 18QHTF21-13.484-PD is a standard 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 is designed for a supply voltage of 1.8V and features a power-down function via standby mode. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates LVCMOS output logic for digital interfacing
• Includes power-down capability through standby mode

Applications

• Battery-powered portable devices
• Compact electronic systems requiring small form factors
• Digital circuits utilizing LVCMOS interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a precise 13.484 MHz clock signal is needed for LVCMOS-compatible logic. The choice is driven by the requirement for a low-profile 2.0x1.6 mm package and 1.8V operation. Consider the power-down feature if energy efficiency during idle states is critical for the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on high-frequency control products. The manufacturer has a long history in quartz crystal production. This specific model represents a standard XO variant optimized for modern surface-mount assembly processes.

Replacement Considerations

Direct substitutes include other 13.484 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin compatibility and electrical specifications before swapping. Cross-reference with similar Mercury models like the 18QHTF21-51.200-PD for form factor consistency.
