18QHTF21-65.112-OE

Overview

The 18QHTF21-65.112-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 65.112 MHz and utilizes LVCMOS output logic. 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, designed for surface-mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware Enable/Disable functionality for power management
• Utilizes a leadless 4-SMD surface-mount package

Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontrollers and FPGAs

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 65.112 MHz timing reference is required with low-voltage operation. The LVCMOS output is suitable for standard digital logic families. Consider the enable/disable feature if power conservation or clock gating is necessary. Verify thermal performance within the specified operating temperature range for the intended environment.

Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltages. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact details require datasheet confirmation. This model represents a standard XO variant optimized for compact electronic designs.

Replacement Considerations

Direct substitutes must match the 65.112 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Cross-reference with other manufacturers offering identical pinouts and electrical characteristics. Ensure equivalent frequency stability and phase noise specifications are met for critical timing applications.
