18QHTF21-37.300-OE

Oscillators Overview

The 18QHTF21-37.300-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 37.3 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, no lead package designed for surface mount applications.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features an enable/disable pin for power management control
• Utilizes a compact 4-SMD no-lead surface mount package

Oscillators Applications

• General clock signal generation in electronic circuits
• Embedded systems requiring precise timing references
• Consumer electronics with low voltage requirements

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues during operation.

Oscillators Selection Notes

Select this component when a 37.3 MHz reference clock is required within a low-voltage 1.8V environment. The choice is driven by the need for a small footprint via the 4-SMD package and the necessity for active control over the oscillator state through the enable pin. Consider thermal performance if operating near the upper temperature limits.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact details require datasheet confirmation. This model represents a standard XO variant within the manufacturer's portfolio.

Oscillators Replacement Considerations

Direct substitutes must match the 37.3 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as current consumption and stability before swapping. Cross-reference with other manufacturers offering similar SMD oscillators if availability is constrained.
