18QHTF21-73.200-OE

Overview

The 18QHTF21-73.200-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 73.2 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an enable/disable control function, allowing for power management through active high or low states. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This oscillator is suitable for digital signal processing and communication systems requiring precise clock signals.

Feature Summary

• Supports LVCMOS output logic for direct interface with digital circuits
• Includes enable/disable functionality for power management
• Compact 4-SMD no-lead package design for space-constrained applications

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required voltage levels and output types. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any recent updates to the pinout configuration or thermal specifications before finalizing procurement decisions.

Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 73.2 MHz applications. Ensure the host circuit supports the 1.8V operating voltage and LVCMOS logic levels. Consider the enable/disable feature if power efficiency is a critical design parameter. Verify that the 2.0x1.6mm footprint fits within the available PCB area constraints.

Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact definitions should be confirmed via official datasheets. It serves as a timing source for modern electronic devices requiring stable clock signals.

Replacement Considerations

Direct substitutes include other 73.2 MHz XO components with compatible 1.8V operation and LVCMOS outputs. Equivalent packages such as 4-SMD no-lead types from other manufacturers may be considered if electrical parameters match. Always verify frequency stability, load capacitance, and drive strength requirements before substituting.
