Oscillators Overview

The 18QHTF21-24.4196-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.4196 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing timing references
• Embedded system clock sources
• Communication module synchronization

Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your circuit design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The integrated enable function makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor if board space is limited. Validate that the 24.4196 MHz frequency meets the specific data rate or clock division needs of the target application without additional frequency synthesis.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These components are engineered for consumer electronics and portable devices where size and power consumption are critical constraints compared to larger through-hole or standard SMD oscillators.

Oscillators Replacement Considerations

Direct replacements must match the 24.4196 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if specified in the original design. Cross-reference with other manufacturers offering similar small-form-factor XO components with enable pins.
