18QHTF21-94.911111-OE

Overview

The 18QHTF21-94.911111-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 94.911111 MHz and utilizes LVCMOS output logic. The device is designed for operation with a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Enable/Disable control functionality for power management
• Compact 4-SMD No Lead surface-mount package design

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance, load capacitance, and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the enable/disable pin configuration matches the host controller's GPIO capabilities to avoid unintended state issues during operation.

Selection Notes

Select this component when a precise 94.911111 MHz clock source is required with low-voltage 1.8V operation. The LVCMOS output ensures compatibility with standard digital logic families. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the enable feature meets power-saving requirements if dynamic clock gating is necessary.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard crystal oscillators. The series offers various frequencies and voltage options. Mercury Electronics is a specialized manufacturer of frequency control products, including quartz crystals and oscillators, with a long history in the industry. This specific model represents a fixed-frequency solution within their broader portfolio.

Replacement Considerations

Direct substitutes must match the 94.911111 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Check equivalent parts from other manufacturers ensuring identical pinout and electrical characteristics. Verify that any alternative maintains the same enable/disable functionality and operating temperature range.
