18QHTF21-73.6363-OE

Overview

The 18QHTF21-73.6363-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 73.6363 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports active enable and disable functionality for power management
• Delivers LVCMOS output signal compatibility
• Utilizes a surface-mount package design

Applications

• General clock generation for digital circuits
• Embedded system timing references
• Consumer electronics timing modules

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage specifications. Ensure the operating temperature range meets application requirements. Cross-reference the part number with authorized distributors to confirm authenticity and availability. Check for any alternate suffixes that may indicate different electrical characteristics or packaging options.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The small form factor suits space-constrained designs. Confirm that the LVCMOS output level matches the input requirements of the downstream logic. Consider the enable pin utility if power conservation during idle states is necessary for the system architecture.

Part Context

This oscillator belongs to the Mercury Electronics 18QHTF series, which focuses on low-voltage, small-footprint clock solutions. The series typically includes various frequencies and voltage options. The '18' prefix generally indicates the 1.8V supply requirement, while 'QHTF' denotes the specific product line characteristics within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes include other 73.6363 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no-lead packages. Verify pinout compatibility and electrical parameters before substitution. Alternative part numbers from the same manufacturer with different suffixes may offer similar performance but require verification of functional differences.
