18QHTF21-17.7344-OE

Oscillators Overview

The 18QHTF21-17.7344-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 17.7344 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital signal compatibility
• Supports active low or high enable/disable control functionality
• Designed for low-voltage operation at 1.8V supply levels

Oscillators Applications

• Embedded systems requiring precise clock timing
• Consumer electronics utilizing low-power microcontrollers
• Industrial control boards needing stable frequency references

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout orientation and electrical tolerances. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the 4-SMD no-lead package matches the PCB footprint specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 17.7344 MHz reference is required for LVCMOS interfaces. Consider the 1.8V operating voltage constraint during system architecture planning. Evaluate the small 2.0x1.6mm form factor against available board space constraints. Verify thermal performance requirements for the intended operating temperature range.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD package. The series supports multiple voltage options and logic types. This specific model provides a 17.7344 MHz output, distinguishing it from other variants like the 8.64 MHz or 50.256 MHz versions in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 17.7344 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Cross-reference pin assignments for enable/disable functionality to ensure compatibility.
