18QHTF21-63.220-OE

Overview

The 18QHTF21-63.220-OE is a 63.22 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes LVCMOS output logic. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated enable/disable control functionality
• Compact surface-mount package design

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design specifications 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 to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 63.22 MHz frequency reference. The LVCMOS output is suitable for standard CMOS logic families. Consider the small 2.0x1.6mm package size if board space is limited. Verify that the enable pin functionality meets your power sequencing needs compared to always-on oscillator alternatives.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile surface-mount oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm footprint. This specific model provides a fixed 63.22 MHz output, distinguishing it from programmable or variable frequency options within the broader product line.

Replacement Considerations

Direct substitutes must match the 1.8V supply, LVCMOS output, 63.22 MHz frequency, and 4-SMD 2.0x1.6mm package. Check datasheets for compatible parts from other manufacturers offering identical electrical parameters and pinout configurations to ensure seamless integration without redesign.
