18QHTF21-13.401563-OE

Overview

The 18QHTF21-13.401563-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.401563 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports active low enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Manufactured using quartz crystal technology for frequency stability

Applications

• Embedded systems requiring precise clock timing
• Consumer electronics with space-constrained designs
• Industrial control modules needing stable oscillation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. 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 any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 13.401563 MHz frequency. The small 2.0x1.6mm footprint makes it suitable for dense PCB layouts. Consider the enable pin feature if dynamic power saving is necessary. Verify that LVCMOS output levels are compatible with the receiving logic inputs of your target application without additional level shifting.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series, specifically designed for general-purpose clocking applications. The '18' prefix typically indicates the 1.8V supply voltage family, while 'QHTF' denotes the specific package type and performance class within their catalog. It is distinct from higher voltage or differential output variants offered by the manufacturer.

Replacement Considerations

Direct substitutes must match the 13.401563 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical electrical specifications and pinout configurations to ensure functional interchangeability without redesigning the host circuit.
