18QHTF21-26.598-OE

Oscillators Overview

The 18QHTF21-26.598-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 26.598 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control functionality. 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 and disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General clock signal generation
• Digital system timing references
• Embedded controller clock sources

Oscillators 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 power rails. Ensure the 4-SMD no-lead footprint matches the PCB land pattern to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS signaling standards. The integrated enable pin allows for power management strategies in battery-operated devices. Consider the small form factor suitable for space-constrained designs where standard leaded packages do not fit.

Oscillators Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products including quartz crystals, oscillators, and filters. The 18QHTF21 series represents their standard XO lineup, offering various frequencies within a unified package style to simplify inventory management for designers.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD no-lead packages from manufacturers such as Epson or NDK, provided the frequency and pinout are identical. Cross-reference electrical specifications carefully to ensure equivalent jitter and phase noise performance.
