18QHTF21-83.000-PD

Overview

The 18QHTF21-83.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 83.0 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications in electronic circuits requiring precise timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Standby (Power Down) functionality to reduce power consumption
• Operates on a 1.8V supply voltage suitable for low-power systems

Applications

• Battery-powered portable devices
• Embedded systems requiring precise clock signals
• Digital communication interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications. Confirm that the 4-SMD No Lead package dimensions align with your PCB footprint. Check for any specific ordering suffixes that may affect performance or availability.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The integrated standby feature makes it suitable for applications needing power efficiency. Consider the 83.0 MHz frequency specifically for timing needs matching this rate. Evaluate the small form factor for space-constrained designs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The manufacturer has been producing frequency control products since 1973. This series typically offers standard XO options with various frequencies and supply voltages, catering to general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 83.0 MHz LVCMOS oscillators with 1.8V supply and 4-SMD packages. Verify pinout compatibility and electrical parameters such as current consumption and phase noise if available. Cross-reference with similar Mercury parts like the 25QHTF22 series if voltage differences are acceptable.
