18QHTF21-14.824-OE

Oscillators Overview

The 18QHTF21-14.824-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 14.824 MHz and utilizes LVCMOS output logic levels. The device requires a supply voltage of 1.8V and includes enable/disable control functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The component is RoHS compliant and designed for surface-mount applications.

Oscillators Feature Summary

• LVCMOS output interface
• Enable/Disable control pin
• RoHS compliant construction

Oscillators Applications

• Embedded systems requiring precise clock signals
• Communication modules
• Consumer electronics devices

Oscillators Procurement Notes

Verify the specific ordering suffix and voltage rating against the target design requirements. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check for RoHS compliance documentation if required by regulatory standards. Validate the enable/disable signal compatibility with the controlling microcontroller or FPGA.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6 mm package is suitable for space-constrained designs. Consider the enable/disable feature for power-sensitive applications. Compare against other frequencies in the QHTF21 series if different clock speeds are needed. Ensure the manufacturing source is Mercury Electronics to guarantee specification adherence.

Oscillators Part Context

This part belongs to the QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, including 2.5V variants like the 25QHTF21 model. The '18' prefix indicates the 1.8V operating voltage, while '14.824' specifies the output frequency. The '-OE' suffix typically denotes the enable/disable functionality.

Oscillators Replacement Considerations

Direct substitutes within the same series include the 25QHTF21-14.824-OE, though it operates at 2.5V instead of 1.8V. Other frequencies in the 18QHTF21 series may be used if the clock speed differs. Verify pinout and electrical characteristics before swapping with generic LVCMOS oscillators.
