18QHTF21-101.010-OE

Overview

The 18QHTF21-101.010-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 101.01 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes an Enable/Disable control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated Enable/Disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low voltage operation

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under your specific environmental conditions.

Selection Notes

Select this component when a stable 101.01 MHz reference is required within a low-voltage 1.8V environment. The LVCMOS output ensures direct interfacing with standard digital logic without additional level shifting. Consider the Enable/Disable feature if power management during idle states is a priority. Verify that the small form factor fits within the spatial limitations of the target application board.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystals and oscillators, offering various packages and voltage options. This specific model represents a mid-frequency option within their portfolio, targeting applications needing precise timing without the complexity of programmable or temperature-compensated variants.

Replacement Considerations

Direct substitutes must match the 101.01 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check equivalent parts from other manufacturers for pinout compatibility and electrical parameter alignment. Ensure any replacement maintains the same enable/disable functionality and physical dimensions for seamless integration.
