18QHTF21-3.579545-OE

Oscillators Overview

The 18QHTF21-3.579545-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 3.579545 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an enable/disable control function to manage power states efficiently. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for power management
• Operates at 1.8V supply voltage
• Housed in a 4-SMD, No Lead surface-mount package

Oscillators Applications

• General-purpose clock signal generation
• Digital system timing references
• Low-power embedded electronics
• Consumer electronic devices requiring precise frequency standards

Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official documentation to confirm the exact enable/disable configuration and pinout. Ensure that the 1.8V supply requirement aligns with the target system's voltage rails. Confirm the 4-SMD, No Lead package dimensions match the PCB footprint design before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a stable 3.579545 MHz reference is required for LVCMOS-compatible circuits. The choice is driven by the need for low-voltage operation at 1.8V and the integration of enable/disable controls for power efficiency. Consider the small form factor of the 4-SMD package for space-constrained designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The '-OE' suffix typically denotes specific operational characteristics or packaging variants within the manufacturer's lineup, distinguishing it from other versions like the '-PD' variant which may feature standby modes.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-3.579545-PD from the same manufacturer, though functional differences in power management modes must be verified. Cross-manufacturer replacements require matching frequency, voltage, output logic, and package dimensions.
