18QHTF21-100.0025-OE

Overview

The 18QHTF21-100.0025-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 100.0025 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Utilizes a small form factor 4-SMD no lead package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded applications utilizing LVCMOS interfaces

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's power rails. Ensure the 4-SMD no lead package footprint matches the PCB layout. Check for any specific ordering suffixes that may affect performance or packaging type as defined by the manufacturer.

Selection Notes

Select this component when a precise 100.0025 MHz clock source is required within a low-voltage 1.8V environment. The LVCMOS output ensures compatibility with standard digital logic families. Consider the physical size constraints due to the 2.0x1.6 mm package. Evaluate the need for enable/disable control if power efficiency is a priority in the application design.

Part Context

This part belongs to the 18QHTF21 series of surface mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltages, including 2.5V options like the 25QHTF21 variant. The 'OE' suffix likely denotes a specific packaging or configuration option provided by the manufacturer for this specific frequency point.

Replacement Considerations

Direct substitutes include other 100 MHz LVCMOS oscillators in similar SMD packages operating at 1.8V. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution. Cross-reference with Mercury United Electronics equivalents if available.
