18QHTF21-83.330-OE

Overview

The 18QHTF21-83.330-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 83.33 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. 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 and disable functionality for power management
• Compact surface-mount package design suitable for space-constrained applications

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

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 specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 83.33 MHz clock source is required with low voltage operation. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the physical size constraints of the 2.0x1.6mm package against available board space. Verify thermal operating range suitability for the intended environment.

Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, designed for high-frequency applications requiring small form factors. The series typically offers standard frequencies with LVCMOS outputs. The 'OE' suffix indicates the inclusion of an enable pin feature, allowing for dynamic control of the oscillator state to conserve power when not in use.

Replacement Considerations

Direct substitutes must match the 83.33 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the enable function placement. Check if alternative manufacturers offer equivalent electrical characteristics and temperature ranges for seamless integration.
