18QHTF21-72.588-OE

Overview

The 18QHTF21-72.588-OE is a 72.588 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features LVCMOS output logic. The device includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise timing signals in low-voltage digital systems.

Feature Summary

• Provides stable 72.588 MHz clock signal generation
• Supports low-voltage 1.8V operation
• Includes enable/disable pin for power control
• Utilizes LVCMOS output interface

Applications

• Digital signal processing circuits
• Communication equipment timing
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Ensure the 1.8V supply voltage matches your system's power rails. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this model when a 72.588 MHz frequency is specifically required for synchronous data transmission or processing. The 1.8V operating voltage makes it suitable for modern low-power portable devices. The enable feature allows for dynamic power saving during idle periods. Consider the small 2.0x1.6mm package size for space-constrained designs.

Part Context

This part belongs to Mercury Electronics' series of surface-mount crystal oscillators. The '18' prefix typically indicates the 1.8V supply voltage family. The 'QHTF' designation relates to the specific package type and performance class within their product line. These components are widely used in consumer electronics and industrial control systems requiring reliable clock sources.

Replacement Considerations

Direct substitutes must match the 72.588 MHz frequency, 1.8V supply, and LVCMOS output. Verify package compatibility with the 4-SMD no-lead 2.0x1.6mm form factor. Other manufacturers offering similar specifications should be evaluated for electrical parameter equivalence and thermal performance under identical operating conditions.
