18QHTF21-69.632-OE

Overview

The 18QHTF21-69.632-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 69.632 MHz with an LVCMOS output logic level. The device requires 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 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes hardware enable/disable control functionality
• Utilizes a leadless surface-mount package design

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded applications utilizing standard SMD footprints

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 to guarantee proper assembly and electrical connectivity.

Selection Notes

Select this component when a precise 69.632 MHz timing source is required within a low-voltage environment. The integrated enable pin allows for power management strategies in battery-operated devices. Consider the small form factor for space-constrained designs while ensuring compatibility with LVCMOS logic levels used in the target application.

Part Context

This part belongs to the 18QHTF series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'OE' suffix typically denotes the presence of an enable control feature, distinguishing it from basic continuous-output variants within the same product family.

Replacement Considerations

Direct substitutes must match the 69.632 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility for the enable function. Cross-reference with other manufacturers offering similar leadless SMD oscillators if Mercury Electronics availability is limited.
