18QHTF21-75.275-OE

Overview

The 18QHTF21-75.275-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.275 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an Enable/Disable control interface for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports Enable/Disable functionality for active power control
• Utilizes LVCMOS output logic for digital interfacing
• Designed in a small form factor SMD package

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the physical footprint matches the PCB layout constraints for the 2.0x1.6 mm package. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 75.275 MHz reference. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small 4-SMD package size for space-constrained layouts. Verify compatibility with LVCMOS input thresholds of the receiving logic circuits.

Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and voltage options. The suffix OE typically denotes the Enable/Disable function variant within this product line. Mercury Electronics specializes in quartz crystals and oscillators, offering a range of frequency control products for industrial and consumer electronics applications.

Replacement Considerations

Direct substitutes may include other 75.275 MHz LVCMOS oscillators from different manufacturers provided they match the 1.8V supply, 4-SMD package dimensions, and enable pin configuration. Cross-reference electrical parameters such as phase noise and jitter specifications to ensure functional equivalence.
