18QHTF21-83.250-OE

Overview

The 18QHTF21-83.250-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 83.25 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead surface mount package with dimensions of 2.00mm x 1.60mm.

Feature Summary

• Integrates Enable/Disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed for surface mount assembly in small form factors

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded microcontroller timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB layout silkscreen and solder mask definitions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a precise 83.25 MHz reference is required within a low-voltage 1.8V environment. The choice is driven by the need for a small 2.0x1.6mm footprint and the necessity for an active enable pin to manage system power states. Compare against other Mercury series oscillators if different frequencies or voltage levels are needed.

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 standard frequencies and supports LVCMOS outputs. The suffix OE indicates the inclusion of an enable control feature, distinguishing it from basic continuous-output variants within the same physical package family.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical 83.25 MHz frequency and 1.8V operation, such as those without the OE suffix if enable control is not utilized. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS oscillators, ensuring pinout and electrical specifications match exactly.
