18QHTF21-4.194304-OE

Oscillators Overview

The 18QHTF21-4.194304-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 4.194304 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function via the OE pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports active enable and disable functionality through the OE pin
• Utilizes LVCMOS output logic for digital interface compatibility
• Operates on a low 1.8V supply voltage

Oscillators Applications

• Embedded systems requiring precise clock timing
• Portable electronic devices with power management needs
• Communication modules utilizing standard serial interfaces

Oscillators Procurement Notes

Verify that the specific part number suffix matches the required enable/disable functionality. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout design. Check that the operating temperature range meets the environmental requirements of the final application.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside dynamic power control capabilities. The enable/disable feature allows for significant power savings in battery-operated applications compared to continuously running oscillators. Consider the small 2.0x1.6 mm footprint if space constraints are critical within the design.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in surface-mount crystal oscillators. The series offers various frequencies and voltage options, with the 'OE' suffix indicating the presence of an output enable pin for power management. This specific variant provides a stable 4.194304 MHz reference signal for digital circuits.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with matching 1.8V specifications and enable functions, such as the 18QHTF21-6.300-OE or 18QHTF21-100.640-OE, provided the frequency difference is acceptable for the application.
